Some of the mov* patterns use ^ and $ constraint modifiers, which mean
give a penalty to this alternative if this operand needs a reload.  They
are meant here to give a penalty if a register operand needs reloading
(because it needs to be in a different kind of register), not when a
memory operand needs reloading (which is easy and cheap to do).

This patch fixes the movdi patterns.  This fixes PR85755.

The following are changed (name, old constraints, new constraints):
FPR store   ^m := d     m := ^d
FPR move    ^d := d     ^d := ^d
AVX store   ^wY := wb   wY := ^wb
AVX store   $Z := wv    Z := $wv
VSX move    ^wi := wi   ^wi := ^wi


	PR target/85755
	* config/rs6000/rs6000.md (*movdi_internal32): Put constraint modifiers
	on the correct operand.
	(*movdi_internal64): Ditto.
