Nate Begeman 8c47c3a3b1 Remove TLI.LowerReturnTo, and just let targets custom lower ISD::RET for 
the same functionality.  This addresses another piece of bug 680.  Next,
on to fixing Alpha VAARG, which I broke last time.

Nate Begeman e74795cd70 First part of bug 680: 
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

Evan Cheng 9cdc16c6d3 * Fix a GlobalAddress lowering bug. 
* Teach DAG combiner about X86ISD::SETCC by adding a TargetLowering hook.

Evan Cheng c1583dbd63 * Added support for X86 RET with an additional operand to specify number of 
bytes to pop off stack.
* Added support for X86 SETCC.

Evan Cheng a74ce62746 * Added lowering hook for external weak global address. It inserts a load 
for Darwin.
* Added lowering hook for ISD::RET. It inserts CopyToRegs for the return
  value (or store / fld / copy to ST(0) for floating point value). This
  eliminate the need to write C++ code to handle RET with variable number
  of operands.
