[powerpc] Use __builtin_{mffs,mtfsf}
Replace inline asm uses of the "mffs" and "mtfsf" instructions with the analogous GCC builtins. __builtin_mffs and __builtin_mtfsf are both available in GCC 5 and above. Given the minimum GCC level for GLibC is now GCC 6.2, it is safe to use these builtins without restriction. 2019-03-29 Paul A. Clarke <pc@us.ibm.com> * sysdeps/powerpc/fpu/fenv_libc.h (fegetenv_register): Replace inline asm with builtin. * sysdeps/powerpc/powerpc64/le/fpu/sfp-machine.h (FP_INIT_ROUNDMODE): Likewise. * sysdeps/powerpc/fpu/tst-setcontext-fpscr.c (_GET_DI_FPSCR): Likewise. (_GET_SI_FPSCR): Likewise. (_SET_SI_FPSCR): Likewise.
