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

functionality of FunctionInfo pass as doFinalization method.
Rename pass to match names of other passes like it.
Rename the pass creator fn to mimic the other creator fn names.
Include StringExtras for utostr().
Make symbol prologue/epilogue stuff redundant with
EmitBytecodeToAssembly, in preparation for refactoring.

some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.
This should hopefully fix the nightly tester.

much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory). This makes the system cleaner and allows us to have a read-only
source tree.

Adjusted Makefile to work with new autoconf-style object root.
Specifically, use the new -I option of tblgen to find include files.

* Generate a single BA instead of 6-instruction JUMP if possible
(this occurs both in the creation and overwriting of the stub code)
* If possible, rewrite the ORIGINAL call to call the generated function
directly, thus bypassing the stub entirely
Also added some statistics on how often calls are overwritten and how often the
CompilationCallback is invoked.

* Break apart saving and restoring registers into separate functions
* Instead of saving single and double FP registers, just save the double
registers -- aliasing helps preserve the single FP registers as well.
* Request just as much memory for a stub as we actually use

rounding up to a page, we need to request (num instrs * 4) bytes. However, I
think that 64 bytes is overkill for the stub function.

registers are global, are NOT windowed, and hence can be clobbered!
* Removed unused register shorthand notations
* Fixed and cleaned up comments in inline assembly

another delayed instr. would cause the later sanity-check (assertion)
in PhyRegAlloc.cpp to fail, even though there is really no error.
