PR 68393: Handle SUBREG_PROMOTED_VAR_P in expand_direct_optab_fn

Do the usual dance when assigning to SUBREG_PROMOTED_VAR_P destinations:
first convert to the outer mode, then extend to the inner mode.

Tested that it fixes the powerpc64le-linux-gnu breakage.  Also tested
on x86_64-linux-gnu and powerpc64-linux-gnu.
