f249c5d5ad Don't try to simplify urem and srem using arithmetic rules that don't work
under modulo (overflow). Fixes PR1933.

8dd2324903 Refine Cell's i64 constant generation code to cover more constants where the
upper and lower 32-bits are the same (in addition to 0 and -1 previously.)

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.

8e6367195e Improve comment, pass in the original VT so that we can shrink a long double constant
all the way to float, not stopping at double.

4ebf6b3b53 Codegen support for i128 UINT_TO_FP. This just fixes a
bug in r47928 (Int64Ty is the correct type for the constant
pool entry here) and removes the asserts, now that the code
is capable of handling i128.

e0b3c221ab Add a target lowering hook to control whether it's worthwhile to compress fp constant.
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.
