ARM: do not use the clang integrated assembler in some cases.

Browse Source 
The integrated assembler of clang does not understand some/all of the
ARM macro assembler syntax used in pixman-arm-neon-asm.S. By default,
this integrated assembler is used when using the "clang" command as a
driver. This patch turns off the integrated assembler of clang for that
file.
