in SPEC, the subsequent optimziations that we are after don't play with

= G;
turning into:
bool G_b;
= G_b ? 412312.312 : 0;

Two bug fixes:
...
1. Actually increment the Statistic for the GV elim optzn
2. When resolving undef branches, only resolve branches in executable blocks,
avoiding marking a bunch of completely dead blocks live. This has a big
impact on the quality of the generated code.
With this patch, we positively rip up vortex, compiling Ut_MoveBytes to a
single memcpy call. In vortex we get this:
12 ipsccp - Number of globals found to be constant
986 ipsccp - Number of arguments constant propagated
1378 ipsccp - Number of basic blocks unreachable
8919 ipsccp - Number of instructions removed

Make GEPs not suck so much:

* Don't emit the Index * ElementSize multiply if Index is a constant.
* Use a shift, not a multiply, if ElementSize is 1/2/4/8.
* If ElementSize fits in the immediate field of SMUL, then put it there.
Fix a bug where struct offsets might be truncated (ConstantSInt::get is
now used instead of ConstantInt::get).
