- I'd appreciate it if someone else eyeballs my changes to make sure I captured
the intent of the test.

linear scan reg alloc. This fixes a problem I ran into where extracting
a function from a larger file caused the generated code to change (masking
the problem I was trying to debug) because the allocator behaved differently.
This changes the results for two X86 regression checks. stack-color-with-reg
is improved, with one less instruction, but pr3495 is worse, with one more
copy. As far as I can tell, these tests were just getting lucky or unlucky,
so I've changed the expected results.

Constant uniquing tables. This allows distinct ConstantExpr objects
with the same operation and different flags.
Even though a ConstantExpr "a + b" is either always overflowing or
never overflowing (due to being a ConstantExpr), it's still necessary
to be able to represent it both with and without overflow flags at
the same time within the IR, because the safety of the flag may
depend on the context of the use. If the constant really does overflow,
it wouldn't ever be safe to use with the flag set, however the use
may be in code that is never actually executed.
This also makes it possible to merge all the flags tests into a single test.

There's a bug with ocamlc that uses "char*" instead of "const char*" for
global string variables. This causes g++ to be very noisy when linking
ocamlc programs. That's why the ocaml test used to cat to /dev/null.
ocamlopt doesn't have this problem, so we can get rid of the >/dev/null,
which may obscure some problems.

with Andreas to figure this out.

instead of a bool argument, and to do the dominator check itself.
This makes it eaiser to use when DominatorTree information is
available.

simplifylibcalls optimization is thus valid for C++ but not C.
It's not important enough to worry about for C++ apps, so just
remove it.

edge-profiling, this is more useful since the loading of the
optimal-edge-profiling is more complicated.
The edge-profiling is tested in edge-profiling.ll where only the
instrumentation is tested.

at the first pointer being indexed. Correct the predicate.
