As a side-effect this also gives it the correct value on e.g. PPC970FX-based
PPC64 systems, thus fixing "make test" (mp2/mp3 decoding).

GCC makes a mess of these operations, so give it a hand.
55% faster MP3 decoding on G4.

Left to its own devices, gcc calculates the full 64-bit product only to
discard the low 32 bits. This forces it to do the right thing.
20% faster MP3 decoding on G4.

h264_idct_add16intra, h264_idct_add8 need to be implemented.
Add C version of ff_h264_idct8_dc_add in AltiVec so that ff_h264_idct8_add_altivec
can be used.

Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).
Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.

similar typedefs that sysctl.h needs. Since sysctl() itself isn't POSIX
undefining _POSIX_C_SOURCE for check_altivec.c seems the best way to fix this.

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_".
