6c788376e9 add a pass that can extract all kinds of global values, not just functions. Update llvm-extract to use it and optionally extract a global variable if you want it too

d1d5887c74 Prefer to use ocamlc.opt to ocamlc and soforth. 
These natively compiled versions are faster.

b33eee09d2 When setting the "unused" info, take into account something like this: 
%r3<def> = OR %x3<kill>, %x3

We don't want to mark the %r3 as unused even though it's a sub-register of %x3.

c29399e54e - Fix support for "special" i64 immediates that can be loaded 
using IL, ILA, et. al. v2i64 and i64 are now supported by
  the select bits (SELB) instruction.

- Add missing comparison operations (testcase forthcoming)

- More multiclass refactoring.

3c19a3950c - Expand tabs to spaces. 
- select_bits.ll now fully functional now that PR1993 is closed. It was
  previously broken by refactoring in SPUInstrInfo.td and using multiclasses.
- Same for eqv.ll

15cc6fabaf This patch fixes a problem encountered by the CellSPU backend where variants 
were being pruned in patterns where a variable was used more than once, e.g.:

  (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC)))

In this example, $rC is used more than once and is actually significant to
instruction selection pattern matching when commuted variants are produced.
This patch scans the pattern's clauses and collects the variables, creating
a set of variables that are used more than once. TreePatternNode::isIsomorphicTo()
also understands that multiply-used variables are significant.

a9fcb187af Generalize FP constant shrinking optimization to apply to any vt 
except ppc long double.  This allows us to shrink constant pool
entries for x86 long double constants, which in turn allows us to
use flds/fldl instead of fldt.
