    expr: Fix up store_expr into SUBREG_PROMOTED_* target [PR108264]

    The following testcase ICEs on s390x-linux (e.g. with -march=3Dz13).
    The problem is that target is (subreg/s/u:SI (reg/v:DI 66 [ x+-4 ]) 4)
    and we call convert_move from temp to the SUBREG_REG of that, expecting
    to extend the value properly.  That works nicely if temp has some
    scalar integer mode (or partial one), but ICEs when temp has V4QImode
    on the assertion that from and to modes have the same bitsize.
    store_expr generally allows say store from V4QI to SI target because
    they have the same size and if temp is a CONST_INT, we already have code
    to convert the constant properly, so the following patch just adds hand=
ling
    of non-scalar integer modes by converting them to the mode of target
    first before convert_move extends them.
