[Bug c/42596] Integer/Floating point vector casts generate XMM register moves from and to the same register

Uh, of course.

_Don't use global register variables_

They are not supposed to be used for this kind of things and nobody spends
a single second to optimizing code generation for them - instead the most
difficult thing is to prevent the compiler from miscompiling things.
