446ae11d7c Allow special-casing of operand printing based on opcode. Print
non-register, non-immed. arguments to SETHI and OR using %hi() and
%lo() respectively.

f3210d2c53 Make -print-machineinstrs even stronger. You get to see the final code after
peepholing, and make it work the same way in the JIT as in LLC.

01cdb1b367 By far, one of the most common uses of isnan is to make 'isunordered'
comparisons.  In an 'isunordered' predicate, which looks like this at
the LLVM level:

        %a = call bool %llvm.isnan(double %X)
        %b = call bool %llvm.isnan(double %Y)
        %COM = or bool %a, %b

We used to generate this code:

        fxch %ST(1)
        fucomip %ST(0), %ST(0)
        setp %AL
        fucomip %ST(0), %ST(0)
        setp %AH
        or %AL, %AH

With this patch, we generate this code:

        fucomip %ST(0), %ST(1)
        fstp %ST(0)
        setp %AL

Which should make alkis happy.  Tested as X86/compare_folding.llx:test1

0ca2c8e02c Now that compare instructions aren't lumped in with the other twoargfp instructions,
we can get rid of the FpUCOM/FpUCOMi pseudo instructions, which makes stuff simpler
and faster.

d62d5d7e5b Split compare instruction handling OUT of handleTwoArgFP into handleCompareFP.
This makes the code much simpler, and the two cases really do belong apart.
Once we do it, it's pretty obvious how flawed the logic was for A != A case,
so I fixed it (fixing PR369).

This also uses freeStackSlotAfter instead of inserting an fxchg then
popStackAfter'ing in the case where there is a dead result (unlikely, but
possible), producing better code.

8fcf797f79 <alloca.h> on cygwin pulls in a ton of stuff (macros and function protos)
that we REALLY don't want in the CBE code.

With this fix, the CBE passes all of the MultiSource tests on cygwin that
it does on linux.  Yaay!

2ffbb6d20a Insert machine instructions generated for Phi nodes into their
corresponding MachineCodeForInstruction vectors.

I need to be able to get the register allocated for the thing which is
called PhiCpRes in this code; this should make that task easier, plus,
Phi nodes are no longer "special" in the sense that their
MachineCodeForInstruction is empty.
