Making them use those macros will also serve to simplify existing code for aliases / symbol versions in various cases, similar to such simplifications for ldbl-opt code. The libm-alias-*.h files sometimes need to include to determine which aliases they should define. At present, this does not work for inclusion from .S files because can define typedefs for old compilers. This patch changes all the and headers to include __ASSEMBLER__ conditionals. Those conditionals disable everything related to C syntax in the __ASSEMBLER__ case, not just the problem typedefs, as that seemed cleanest. The __HAVE_* definitions remain in the __ASSEMBLER__ case, as those provide information that is required to define the correct set of aliases. Tested with build-many-glibcs.py for a representative set of configurations (x86_64-linux-gnu i686-linux-gnu ia64-linux-gnu powerpc64le-linux-gnu mips64-linux-gnu-n64 sparc64-linux-gnu) with GCC 6. Also tested with GCC 6 for i686-linux-gnu in conjunction with changes to use alias macros in .S files.
