I've just committed this patch. It doesn't change anything externally 
visible; it's just a code clean up that prepares the way for another 
patch I have in development.

There's no rule how these non-standard "*_exec" patterns should look, 
but every one but this has the exec-mask operand last except this one.

Patch

amdgcn: Swap mov<mode>_exec operands

Every other *_exec insn has the exec operand last.  This being the other way
around is a cause of bugs, and prevents use in macro templates.

	gcc/
	* config/gcn/gcn-valu.md (mov<mode>_exec): Swap the numbers on operands
	2 and 3.
	(mov<mode>_exec): Likewise.
	(trunc<vndi><mode>2_exec): Swap parameters to gen_mov<mode>_exec.
	(<convop><mode><vndi>2_exec): Likewise.
