* Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.
...
* Added a pseudo instruction (for each target) that represent "return void".
This is a workaround for lack of optional flag operand (return void is not
lowered so it does not have a flag operand.)

Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patterns
...
that were overloaded to work before and after the stackifier runs. With the
new clean world, it is possible to write patterns for these instructions: woo!
This also adds a few simple patterns here and there, though there are a lot
still missing. These should be easy to add though. :)
See the comments under "Floating Point Stack Support" for more details on
the new world order.
This patch as absolutely no effect on the generated code, woo!

* 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.
