Make this pass substantially stronger by having it delete dead return values
...
as well as arguments. Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead. This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,
...
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.
This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version. Because these instructions are very common, this
can save a LOT of code space. For example, I sampled two benchmarks, 176.gcc
and 254.gap.
BM Old New Reduction
176.gcc 2673621 2548962 4.89%
254.gap 498261 475104 4.87%
Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc. Not bad.
Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

Completely rewrite support for the Value::use_* list. Now, all operations on
...
this list (except use_size()) are constant time. Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.
This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:
176.gcc: 77.07s -> 37.38s
177.mesa: 7.59s -> 5.57s
252.eon: 21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap: 7.25s -> 7.42s
252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.

Checkin an improvement contributed by Bill:
...
Only transform call sites in a setjmp'ing function which are reachable from
the setjmp. If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.
This dramatically reduces the number of invoke instructions created in some
large testcases.

* Fix isFPCSafeToPrint to find more constants safe to print, which it was

scope instead of function scope. This speeds FP programs quite a bit.

Major refactoring of the bytecode reader. This includes the following
...
changes:
* BytecodeReader::getType(...) used to return a null pointer
on error. This was only checked about half the time. Now we convert
it to throw an exception, and delete the half that checked for error.
This was checked in before, but psmith crashed and lost the change :(
* insertValue no longer returns -1 on error, so callers don't need to
check for it.
* Substantial rewrite of InstructionReader.cpp, to use more efficient,
simpler, data structures. This provides another 5% speedup. This also
makes the code much easier to read and understand.

Eliminate the old LateResolveValues data structure, replacing it with a

new, simpler, ForwardReferences data structure. This is just the first
simple replacement, subsequent changes will improve the code more.
This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement. This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.

This patch substantially simplifies and cleans up handling of basic blocks
...
in the bytecode parser. Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values. For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.
This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s. More speedups to
follow later.

Speed up the predicate used to decide when to inline by caching the size

of callees between executions.
On eon, in release mode, this changes the inliner from taking 11.5712s
to taking 2.2066s. In debug mode, it went from taking 14.4148s to
taking 7.0745s. In release mode, this is a 24.7% speedup of gccas, in
debug mode, it's a total speedup of 11.7%.
This also makes it slightly more aggressive. This could be because we
are not judging the size of the functions quite as accurately as before.
When we start looking at the performance of the generated code, this can
be investigated further.

This changes the PromoteMemToReg function to create "pruned" SSA form, not
...
"minimal" SSA form (in other words, it doesn't insert dead PHIs). This
speeds up the mem2reg pass very significantly because it doesn't have to
do a lot of frivolous work in many common cases.
In the 252.eon function I have been playing with, this doesn't even insert
the 120 PHI nodes that it used to which were trivially dead (in the process
of promoting 356 alloca instructions overall). This speeds up the mem2reg
pass from 1.2459s to 0.1284s. More significantly, the DCE pass used to take
2.4138s to remove the 120 dead PHI nodes that mem2reg constructed, now it
takes 0.0134s (which is the time to scan the function and decide that there
is nothing dead). So overall, on this one function, we speed things up a
total of 3.5179s, which is a 24.8x speedup! :)
This change is tested by the Mem2Reg/2003-10-05-DeadPHIInsertion.ll test,
which now passes.

Speed up the mem2reg transform for allocas which are only read/written in a single
...
basic block. This is amazingly common in code generated by the C/C++ front-ends.
This change makes it not have to insert ANY phi nodes, whereas before it would insert
a ton of dead ones which DCE would have to clean up.
Thus, this fix improves compile-time performance of these trivial allocas in two ways:
1. It doesn't have to do the walking and book-keeping for renaming
2. It does not insert dead phi nodes for them which would have to
subsequently be cleaned up.
On my favorite testcase from 252.eon, this special case handles 305 out of
356 promoted allocas in the function. It speeds up the mem2reg pass from 7.5256s
to 1.2505s. It inserts 677 fewer dead PHI nodes, which speeds up a subsequent
-dce pass from 18.7524s to 2.4806s.
There are still 120 trivially dead PHI nodes being inserted for variables used
in multiple basic blocks, but they are not handled by this patch.

* Update file header comment

*** Revamp the code which handled unreachable code in the function. Now the
code is much more efficient for high-degree basic blocks, such as those
that occur in the 252.eon SPEC benchmark.
For the interested, the time to promote a SINGLE alloca in _ZN7mrScene4ReadERSi
function used to be > 3.5s. Now it is < .075s. The function has a LOT of
allocas in it, so it appeared to be infinite looping, this should make it much
nicer. :)

This checkin basically amounts to a complete rewrite of the type-resolution
...
machinery. This dramatically simplifies how things works, removes irritating
little corner cases, and overall improves speed and reliability.
Highlights of this change are:
1. The exponential algorithm built into the code is now gone. For example
the time to disassemble one bytecode file from the mesa benchmark went
from taking 12.5s to taking 0.16s.
2. The linker bugs should be dramatically reduced. The one remaining bug
has to do with constant handling, which I actually introduced in
"union-find" checkins.
3. The code is much easier to follow, as a result of fewer special cases.
It's probably also smaller. yaay.

Suggestions made by Chris:
...
* Instead of a #define, use inline function
* Fix the name on the #define, errr... now inline function to be more logical:
it doesn't CHECK the alignment, it PERFORMS the alignment
* To get string name of a Type*, use getDescription(), not getName()

Convert PhyRegAlloc into a proper pass.

PhyRegAlloc.cpp:
Don't include TargetMachine.h or TargetRegInfo.h, because these are provided

Merge class RegisterAllocator into class PhyRegAlloc.
Simplify & move ctor, dtor to PhyRegAlloc.h.
Make some of PhyRegAlloc's reference members into pointer members,
so they can be more easily messed with.
MarkAllocatedRegs() becomes a member method, with fewer args.
PhyRegAlloc.h:
Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
TargetRegInfo forward.
Give AddedInstrns the obvious clear() method.
Make some of PhyRegAlloc's reference members into pointer members,
so they can be more easily messed with.
Add prototype for markAllocatedRegs().
Remove unused inline void constructLiveRanges().

Removed linking functionality from gccld.cpp and moved it to linker.cpp.
...
Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.
