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.
