Reid Spencer 1e960cd4fd Implement use of new IntrinsicLowering interface.

Nick Lewycky 0c49722b36 Fix compile error "jump to case label crosses initialization". 
What compiler are people using that accepts this code?

Anton Korobeynikov 037c867b54 Propagate changes from my local tree. This patch includes: 
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.

Evan Cheng 3c9dc6bd46 Conditional branch being fixed up is not the last MI in the BB, there is a 
unconditional branch following it. Simply invert the condition and swap
destinations if the conditional branch can reach the destination of the
unconditional branch:
beq L1
b   L2
=>
bne L2
b   L1

Evan Cheng 1e270b639d SplitBlockBeforeInstr() insert a unconditional branch to the next BB. This 
is unnecessary when we are fixing up a conditional branch since we will be
adding a unconditional branch to the destination of the original branch.

Evan Cheng 5acf2fbb43 - Tell PEI that PPC will handle stack frame rounding itself. 
- Do not round up to max. alignment of stack object if it is > stack alignment.
  It will have to be handled with dynamic aligning code.

Evan Cheng c0b7366cf9 - Reorg Thumb load / store instructions. Combine each rr and ri pair of 
instructions into one (e.g. tLDRrr, tLDRri -> tLDR).
- Thumb ldrsb and ldrsh only have the [reg, reg] address format. If the
  address is not an add, materialize a 0 immediate into a register and use
  it as the offset field.
