d5a5598198 build: check if AS supports the '.func' directive
Not supported by Clang's integrated assembler. Since it just adds
debug information it can safely omitted.

68a06b3a63 aarch64: use '#' for whole line asm comments
Both gnu as and clang treat lines starting with '#' as comments if they
aren't consumed by the C-style preprocessor.
Using '//' does not work with clang since comments are removed before
macro expansion.

6a0fa4d86f aarch64: remove optional :pg_hi21: for adrp instruction

08cd92144e aarch64: Use the correct syntax for relocations
This fixes building in PIC mode with gas. The examples in the gas
manual showed using a # here even though gas itself actually didn't
support that syntax (and the gas test suite only tests it without
the extra hash sign).

dbd12523a4 aarch64: float_dsp NEON assembler
Ported from arm NEON and added vector_dmul_scalar.

Functions between 1.5 and 5 times faster than the C implementations
using Apple's clang-503.0.19 on A7.

b7b17ed66e aarch64: add cpuflags support for NEON and VFP
NEON and VFP are currently mandatory for all ARMv8 profiles. Both are
handled as extensions as far as cpuflags are concerned. This is
consistent with handling x86_64 which always has SSE2, but still
handles it as an extension.
