This adds validation tests for the inline functions for SSE2/SSE3 and
verification that no undefined builtin functions are referenced by the
respective MMX/SSE tests. I would have (to uncover more problems)
changed
the "dg-do compile" to "dg-do assemble" (to also cover the case of bad
assembly generated) if I wasn't told not to modify pre-existing tests.

This patch alone will cause various failure for ix86 and x86-64 in the
modified tests, but since the fixes for these failures are independent
of one another they will be subsequently submitted.

	* gcc.dg/i386-mmx-[12].c: Force error for references to
undefined builtins.
	* gcc.dg/i386-sse-[12].c: Dito.
	* gcc.dg/i386-sse2-[12].c: New tests to validate SSE2 inline
functions.
	* gcc.dg/i386-sse3-[12].c: New tests to validate SSE3 inline
functions.
