Paul Murphy 84d74e427a powerpc: Cleanup fenv_private.h 
Some of the masks are wrong, and the naming is confusing.

There are two basic cases we really care about:

1. Stacking a new rounding mode when running certain
   sections of code, and pausing exception handling.

2. Likewise, but discarding any exceptions which occur
   while running under the new rounding mode.

libc_feholdexcept_setround_ppc_ctx has been removed as it basically
does the same thing as libc_feholdsetround_ppc_ctx but also clearing
any sticky bits.  The restore behavior is what differentiates these
two cases as the SET_RESTORE_ROUND{,_NOEX} macros will either merge
or discard all exceptions occurring during scope of their usage.

Likewise, there are a number of routines to swap, replace,
or merge FP environments.  This change reduces much of
the common and sometimes wrong code.

Tested on ppc64le, with results before and after.
