needed for DECLARE_ALIGNED.
Remove dependency from swscale-example.c to swscale_internal.h by duplicating
the necessary code. The duplicated code is a hack and should be removed once a
cleaner pixel format information system exists. swscale-example.c is example
code on how to use the library and therefore shouldn't rely on internal
headers.

Neither the asm() nor the __asm__() keyword is not 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 synta.
