Dan Gohman 40503396da Eliminate more uses of llvm-as and llvm-dis.

Dan Gohman a5b9645c4b 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:

Evan Cheng 4f0d21592a If SSE2 is available, x86 should pass first 3 f32/f64 arguments in XMM registers for fastcc calls.

Dale Johannesen ea3aa5bf11 Remove -unwind-tables-optional everywhere, since
this is now the default.

Dale Johannesen 5169fa17b5 Rename -disable-required-unwind-tables to -unwind-tables-optional.

Dale Johannesen da298f9107 Add -disable-required-unwind-tables to tests
that need it (usually, grepping for some string
found in unwind info)

Dale Johannesen 0de94a1712 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.)

Evan Cheng ebb8540067 Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses.

Chris Lattner 687dbf1a99 tcl seems to hate |& for some reason.

Chris Lattner 0e92458068 switch this to use fastcc to avoid fpstack traffic on x86-32. Switch to
using the count script instead of wc -l

Evan Cheng 5c6d53d2ff Update test case. A spill should now be deleted.

Evan Cheng 2814fe847d Now capable of rematerializing coalesced live intervals.

Dan Gohman fa3eeeedc0 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.
