analyzer: Fix maybe_undo_optimize_bit_field_compare vs non-scalar types [PR113983]

After r14-6419-g4eaaf7f5a378e8, maybe_undo_optimize_bit_field_compare would ICE on
vector CST but this function really should be checking if we had integer types so
reject non-integral types early on (like it was doing for non-char type before r14-6419-g4eaaf7f5a378e8).

Committed as obvious after build and tested for aarch64-linux-gnu with no regressions.

	PR analyzer/113983
