a8e603b719 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.

c66e996765 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.

287e3fc88b Fix for PR#366. We use getClassB() so that we can handle cast instructions 
that cast to bool.

accounted for in the map (at least, in its current format).

42730da855 <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!

b4f49d8da5 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.

a49f11bec4 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.
