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.

gcc/analyzer/ChangeLog:
* region-model-manager.cc (maybe_undo_optimize_bit_field_compare):
Reject
non integral types.
