ae94e59416 Re-did 60519. It turns out Darwin's handling of hidden visibility symbols are a bit more complicate than I expected. Both declarations and weak definitions still need a stub indirection. However, the stubs are in data section and they contain the addresses of the actual symbols.

3831005eb1 Rewrite code that 1) filters loops and 2) calculates new loop bounds. 
This fixes many bugs. I will add more test cases in a separate check-in.

Some day, the code that manipulates CFG and updates dom. info could use refactoring help.

cc18827f59 CellSPU: Fix bug 3055 
- Add v4f32, v2f64 to LowerVECTOR_SHUFFLE
- Look for vector rotate in shuffle elements, generate a vector rotate
  instead of a full-blown shuffle when opportunity presents itself.
- Generate larger test harness and fix a few interesting but obscure bugs.

30ee7df71c CellSPU: 
- First patch from Nehal Desai, a new contributor at Aerospace. Nehal's patch
  fixes sign/zero/any-extending loads for integers and floating point. Example
  code, compiled w/o debugging or optimization where he first noticed the bug:

  int main(void) {
    float a = 99.0;
    printf("%d\n", a);
    return 0;
  }

  Verified that this code actually works on a Cell SPU.

Changes by Scott Michel:
- Fix bug in the value type list constructed by SPUISD::LDRESULT to include
  both the load result's result and chain, not just the chain alone.
- Simplify LowerLOAD and remove extraneous and unnecessary chains.
- Remove unused SPUISD pseudo instructions.

421fa9e32e Teach jump threading some more simple tricks: 
1) have it fold "br undef", which does occur with
   surprising frequency as jump threading iterates.
2) teach j-t to delete dead blocks.  This removes the successor
   edges, reducing the in-edges of other blocks, allowing 
   recursive simplification.
3) Fold things like:
     br COND, BBX, BBY
  BBX:
     br COND, BBZ, BBW

   which also happens because jump threading iterates.

62c939d7d5 Mark x86's V_SET0 and V_SETALLONES with isSimpleLoad, and teach X86's 
foldMemoryOperand how to "fold" them, by converting them into constant-pool
loads. When they aren't folded, they use xorps/cmpeqd, but for example when
register pressure is high, they may now be folded as memory operands, which
reduces register pressure.

Also, mark V_SET0 isAsCheapAsAMove so that two-address-elimination will
remat it instead of copying zeros around (V_SETALLONES was already marked).

e4300e271a Fix byval arguments in the fastcc calling convention. The fastcc convention 
delegates to the regular x86-32 convention which handles byval, but only

handling those cases. This fixes PR3122 (and rdar://6400815), llvm-gcc

96da041949 Remove a (what appears to be) overly strict assertion. Here is what happened: 
1. ppcf128 select is expanded to f64 select's.
2. f64 select operand 0 is an i1 truncate, it's promoted to i32 zero_extend.
3. f64 select is updated. It's changed back to a "NewNode" and being re-analyzed.
4. f64 select operands are being processed. Operand 0 is a "NewNode". It's being expunged out of ReplacedValues map.
5. ExpungeNode tries to remap f64 select and notice it's a "NewNode" and assert.
Duncan, please take a look. Thanks.
