Fix powerpc fesetexceptflag clearing FE_INVALID (bug 20455).
As shown by the test math/test-fexcept, the powerpc fesetexceptflag implementation fails to clear a previously set FE_INVALID flag, when that flag is clear in the saved exceptions and FE_INVALID is included in the mask of flags to restore, because it fails to mask out the sub-exceptions of FE_INVALID from the FPSCR state. This patch fixes the masking logic accordingly. Tested for powerpc. [BZ #20455] * sysdeps/powerpc/fpu/fsetexcptflg.c (__fesetexceptflag): Mask out all FE_INVALID sub-exceptions from FPSCR when FE_INVALID specified to be restored.
