[Bug target/19010] New: sse and mmx parameter passing broken

["rth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compile the attached test case with option sets "", "-mmmx", "-m3dnow",
"-msse", "-msse2", "-msse2 -m3dnow".

Compilation will succeed with only "", "-m3dnow", and "-msse2 -m3dnow".
The others will ICE in various ways as the ABI selected specifies what
to do with the vector modes in question, but we lack the instructions
to implement the register moves in the completely obvious manner.
