41adb0d679 Improve X86 subtarget support for Windows and AMD.

c52ad4f04e Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it
faster.  This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).

It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change.  Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.

This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.

456a93afce Several major changes:
1. Pull out the expand cases for BSWAP and CT* into a separate function,
   reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
   iterative.  It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.

8137c9e41d Eliminate the need for ExpandOp to set 'needsanotheriteration', as it already
relegalizes the stuff it returns.

Add the ability to custom expand ADD/SUB, so that targets don't need to deal
with ADD_PARTS/SUB_PARTS if they don't want.

Fix some obscure potential bugs and simplify code.

it isn't (likely a TokenFactor), then do not allow the folding.

896811180f * Eliminate FAKE_SOURCES
* Make runtimes and projects build with the new front-end by not relying on
  'llvm-gcc -c' to build a .bc file.  Instead, use llvm-gcc -S -emit-llvm,
  then an explicit invocation of gccas.  Also, don't use llvm-gcc to link
  .bc files together, use gccld directly.
