Not supported by Clang's integrated assembler. Since it just adds
debug information it can safely omitted.

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.

Clang's integrated assembler does not support it.

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).

Based on e3fec3f0 for arm.

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.

This saves one instruction in the x86-64 assembly.

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
