Use trunc functions not __trunc 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 __trunc functions to call the corresponding trunc names instead, with asm redirection to __trunc when the calls are not inlined. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (trunc): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_trunc.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_truncf.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_trunc.c: Likewise. * sysdeps/ieee754/float128/s_truncf128.c: Likewise. * sysdeps/ieee754/dbl-64/s_trunc.c: Likewise. * sysdeps/ieee754/flt-32/s_truncf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_truncl.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc_template.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_truncl.c: Likewise.
