i386: Improved insv of DImode/DFmode {high,low}parts into TImode.
This is the next piece towards a fix for (the x86_64 ABI issues affecting)
PR 88873. This patch generalizes the recent tweak to ix86_expand_move
for setting the highpart of a TImode reg from a DImode source using
*insvti_highpart_1, to handle both DImode and DFmode sources, and also
use the recently added *insvti_lowpart_1 for setting the lowpart.
Although this is another intermediate step (not yet a fix), towards
enabling *insvti and *concat* patterns to be candidates for TImode STV
(by using V2DI/V2DF instructions), it already improves things a little.
