- Use XORP* to implement fneg.

259e97cc72 * Fix 80-column violations
* Rename hasSSE -> hasSSE1 to avoid my continual confusion with 'has any SSE'.
* Add inline asm constraint specification.

6dab05363f Always use FP stack instructions to perform i64 to f64 as well as f64 to i64
conversions. SSE does not have instructions to handle these tasks.

ee625573b5 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.

acc398c195 First part of bug 680:
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

b077b842b6 * 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.
