expand: Fix ICE in store_bit_field_using_insv [PR93235]
The following testcase ICEs on aarch64. The problem is that
op0 is (subreg:HI (reg:HF ...) 0) and because we can't create a SUBREG of a
SUBREG and aarch64 doesn't have HImode insv, only SImode insv,
store_bit_field_using_insv tries to create (subreg:SI (reg:HF ...) 0)
which is not valid for the target and so gen_rtx_SUBREG ICEs.
The following patch fixes it by punting if the to be created SUBREG
doesn't validate, callers of store_bit_field_using_insv can handle
the fallback.
