Support bits/floatn.h inclusion from .S files.
Further _FloatN / _FloatNx type alias support will involve making architecture-specific .S files use the common macros for libm function aliases. 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 <bits/floatn.h> to determine which aliases they should define. At present, this does not work for inclusion from .S files because <bits/floatn.h> can define typedefs for old compilers. This patch changes all the <bits/floatn.h> and <bits/floatn-common.h> 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. * bits/floatn-common.h [!__ASSEMBLER]: Disable everything related to C syntax instead of availability and properties of types. * bits/floatn.h [!__ASSEMBLER]: Likewise. * sysdeps/ia64/bits/floatn.h [!__ASSEMBLER]: Likewise. * sysdeps/ieee754/ldbl-128/bits/floatn.h [!__ASSEMBLER]: Likewise. * sysdeps/mips/ieee754/bits/floatn.h [!__ASSEMBLER]: Likewise. * sysdeps/powerpc/bits/floatn.h [!__ASSEMBLER]: Likewise. * sysdeps/x86/bits/floatn.h [!__ASSEMBLER]: Likewise.
