68d2e3557f Specify a more specific triple for constant-pool-remat-0.ll
Instead of specifying 32-bit x86, specify 32-bit x86 linux.

This test is testing a very specific behavior which changed with
WinCOFF's constant pools.

2346df4d41 Disable statistics on Release builds and move tests that depend on -stats.
Summary:
Statistics are still available in Release+Asserts (any +Asserts builds),
and stats can also be turned on with LLVM_ENABLE_STATS.

Move some of the FastISel stats that were moved under DEBUG()
back out of DEBUG(), since stats are disabled across the board now.

Many tests depend on grepping "-stats" output.  Move those into
a orig_dir/Stats/. so that they can be marked as unsupported
when building without statistics.

613bcf88be When dead code elimination removes all but one use, try to fold the single def into the remaining use.
Rematerialization can leave single-use loads behind that we might as well fold whenever possible.

output to standard output also.

5f6f8101d5 Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

d9a5b77269 Mark functions in some tests as 'nounwind'. Generating
EH info for these functions causes the tests to fail for
random reasons (e.g. looking for 'or' or counting lines
with asm-printer; labels count as lines.)

a76ba56608 switch this to use fastcc to avoid fpstack traffic on x86-32. Switch to
using the count script instead of wc -l

a599a813d5 Mark the SSE and MMX load instructions that
X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.
