[Bug target/18916] [4.0 Regression] mis-aligned vector code with copy memory (-maltivec)

This is a problem with the gcc's function call machinery.  The underlying
problem is that mem alignment of function args is taken from the type of the
arg, not the alignment given by function_arg_boundary.  At least, that's what
I'm seeing on investigating why g++.dg/ext/altivec-3.C is failing on
powerpc64-linux, and this looks like the same bug.
