This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.
