fda2cce3bf Quick hack to get this file compiling again on Mac OS X. The right thing to do
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include <cmath>**, instead of doing it the easy
way with AC_CHECK_FUNCS().

f6d023312f Add two options to the program:
-release causes ENABLE_OPTIMIZED=1 to be added to the make line so that
         the test runs against optimized code.
-pedantic causes the CompileOptimizeOpts variable to be overridden to
          add several additional warnings not picked up by -Wall. This
	  should help catch additional programming faux pas. See the diff
	  for the specific details.

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

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.
