Simplify handling compiler handling in MMX code

Instead of using the parameters --param inline-unit-growth=10000 and
--param large-function-growth=10000", just make the inline functions
__always_inline__.

Also support Intel's compiler in pixman-mmx.c.

Based on a patch by Serhat <ubunturk@gmail.com>
