Use rint functions not __rint functions in glibc libm.
Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __rint functions to call the corresponding rint names instead, with asm redirection to __rint when the calls are not inlined. The x86_64 math_private.h is removed as no longer useful after this patch. This patch is relative to a tree with my floor patch <https://sourceware.org/ml/libc-alpha/2018-09/msg00148.html> applied, and much the same considerations arise regarding possibly replacing an IFUNC call with a direct inline expansion. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (rint): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_rint.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_rintf.c: Likewise. * sysdeps/alpha/fpu/s_rint.c: Likewise. * sysdeps/alpha/fpu/s_rintf.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/ieee754/dbl-64/s_rint.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_rint.c: Likewise. * sysdeps/ieee754/float128/s_rintf128.c: Likewise. * sysdeps/ieee754/flt-32/s_rintf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_rintl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_rintl.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rint.c: Likewise. * sysdeps/m68k/coldfire/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintl.c: Likewise. * sysdeps/powerpc/fpu/s_rint.c: Likewise. * sysdeps/powerpc/fpu/s_rintf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Likewise. * sysdeps/riscv/rvf/s_rintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rint.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/x86_64/fpu/math_private.h: Remove file. * math/e_scalb.c (invalid_fn): Use rint functions instead of __rint variants. * math/e_scalbf.c (invalid_fn): Likewise. * math/e_scalbl.c (invalid_fn): Likewise. * sysdeps/ieee754/dbl-64/e_gamma_r.c (__ieee754_gamma_r): Likewise. * sysdeps/ieee754/flt-32/e_gammaf_r.c (__ieee754_gammaf_r): Likewise. * sysdeps/ieee754/k_standard.c (__kernel_standard): Likewise. * sysdeps/ieee754/k_standardl.c (__kernel_standard_l): Likewise. * sysdeps/ieee754/ldbl-128/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/ieee754/ldbl-96/e_gammal_r.c (__ieee754_gammal_r): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrint.c (__llrint): Likewise. * sysdeps/powerpc/powerpc32/fpu/s_llrintf.c (__llrintf): Likewise.
