b10bed8a63 Constant pointer refs are causing these to fail unnecessarily, which is causing 
a lot of code to be pessimized.  I hate CPRs.  :(

c3cc71abbc 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.

being recomputed unnecessarily.

253.perlbmk, & 300.twolf.  IOW, all SPEC INT and FP benchmarks now link.

7685ac8d35 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.

531922aaca Reverting back to the previous revision. 
We want to check for length 5 because we might get the "llvm." string as the
name.  That string is in the LLVM namespace and should be checked as such.
We also don't have to worry about garbage data because (I believe) the string
class will return a valid value.  So, the switch statement will work and we
don't have to worry about the code wandering into segfault land.

21ca6ee7cd Modified the check for intrinsic functions. All intrinsic functions have to 
be at least 6 characters, since something must follow the "llvm." string in the
function name.
This seems to fix an assertion failure with the SingleSource tests, too.

dd4b421516 Change the code to no longer compute the "type description" immediately when 
the type is analyzed.  Instead, only compute it when requested (with
getDescription), and cached for reuse later.

This dramatically speeds up LLVM in general because these descriptions almost
_never_ need to be constructed.  The only time they are used is when a type is
<<'d.  Printing of modules by themselves uses other code to print symbolic
types when possible, so these descriptions are really only used for debugging.

Also, this fixes the particularly bad case when lots of types get resolved to
each other, such as during linking of large programs.  In these cases, the type
descriptions would be repeatedly recomputed and discarded even though: A. noone
reads the description before it gets resolved, and B. many many resolutions
happen at intermediate steps, causing a HUGE waste of time.

Overall, this makes the getTypeDesc function much more light-weight, and fixes
bug: Assembler/2002-07-08-HugePerformanceProblem.llx, which went from taking
1048.770u/19.150s (which is 17.5 MINUTES, on apoc), to taking 0.020u/0.000s,
which is a nice little speedup.  :)

4e4caeffbd Fix a nasty problem with dominance calculation for unreachable blocks. 
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
