Paul A. Clarke fec2bd2c2d [powerpc] fesetenv: optimize FPSCR access 
fesetenv() reads the current value of the Floating-Point Status and Control
Register (FPSCR) to determine the difference between the current state of
exception enables and the newly requested state.  All of these bits are also
returned by the lighter weight 'mffsl' instruction used by fegetenv_status().
Use that instead.

Also, remove a local macro _FPU_MASK_ALL in favor of a common macro,
FPU_ENABLES_MASK from fenv_libc.h.

Finally, use a local variable ('new') in favor of a pointer dereference
('*envp').
