Clang's integrated assembler (after 3.4) does not yet support the
'.altmacro' directive which is only used in arm asm. Support is planned:
http://llvm.org/bugs/show_bug.cgi?id=18918
Move the GNU as check before the arch specific asm checks since the .dn
check requires gas compatible assembler.
Disable the VC-1 motion compensation NEON asm which is the only part
using that directive. The integrated assembler in the upcoming clang 3.5
does not support .dn/.qn without plans to change that. Too much effort
to implement it while it is rarely used.
http://llvm.org/bugs/show_bug.cgi?id=18199.
Clang Undefined Behaviour Sanitizer seems to make non-constant constant
expressions, making the compilation fail when they are used within
inline assembly if no optimization is requested.
Add -O1 to the cflags to hide the misbehaviour.

It leverages the new hwaccel 1.2 features:
- get_buffer2 is never called
- the internal context is automatically initialized/deinitialized

Build 13 has a crucial fix which makes x265_encode_headers work
as its always been documented.
Previous to this, the check was incorrect.
Also allows for use of the repeat headers flag.

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we
need to explicitly disable it for these architectures.
