Most libm routines depend on the rounding mode and/or set exception
flags, so they are not pure.  Remove the __pure2 annotation from them.
I believe that the following routines and their float and long double
counterparts are the only ones here that can be __pure2:

	copysign is* fabs finite fmax fmin fpclassify ilogb nan signbit

When gcc supports FENV_ACCESS, perhaps there will be a new annotation
that allows the other functions to be considered pure when FENV_ACCESS
is off.

Discussed with:	bde
