Add narrowing divide functions.
This patch adds the narrowing divide functions from TS 18661-1 to glibc's libm: fdiv, fdivl, ddivl, f32divf64, f32divf32x, f32xdivf64 for all configurations; f32divf64x, f32divf128, f64divf64x, f64divf128, f32xdivf64x, f32xdivf128, f64xdivf128 for configurations with _Float64x and _Float128; __nldbl_ddivl for ldbl-opt. The changes are mostly essentially the same as for the other narrowing functions, so the description of those generally applies to this patch as well. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add div. (libm-test-funcs-narrow): Likewise. * math/Versions (GLIBC_2.28): Add narrowing divide functions. * math/bits/mathcalls-narrow.h (div): Use __MATHCALL_NARROW. * math/gen-auto-libm-tests.c (test_functions): Add div. * math/math-narrow.h (CHECK_NARROW_DIV): New macro. (NARROW_DIV_ROUND_TO_ODD): Likewise. (NARROW_DIV_TRIVIAL): Likewise. * sysdeps/ieee754/float128/float128_private.h (__fdivl): New macro. (__ddivl): Likewise. * sysdeps/ieee754/ldbl-opt/Makefile (libnldbl-calls): Add fdiv and ddiv. (CFLAGS-nldbl-ddiv.c): New variable.
