58fe459e36 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!

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.

3d36a9f6f4 Several things: 
1. Remove redundant type casts now that PR673 is implemented.
2. Implement the OUT*ir instructions correctly.  The port number really
   *is* a 16-bit value, but the patterns should only match if the number
   is 0-255.  Update the patterns so they now match.
3. Fix patterns for shifts to reflect that the shift amount is always an
   i8, not an i16 as they were believed to be before.  This previous fib
   stopped working when we started knowing that CL has type i8.
4. Change use of i16i8imm in SH*ri patterns to all be imm.

b822abade7 Give ADJCALLSTACKDOWN/UP the correct operands. 
Give a whole bunch of other stuff variable operands, particularly FP.  The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable.  This will have to be fixed before we can dag->dag
the X86 backend.  The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.
