ab8deccb82 Introduce a new FP instruction type to separate the compare cases from the 
twoarg cases.

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.

9d1af97d02 Fix the big regression that has been killing the nightly tester these last 
few days.  Apparently the old symbol table used to auto rename collisions in
the type symbol table and the new one does not.  It doesn't really make sense
for the new one to do so, so we just make the client do it.
