analyzer: fix ICE with negative bit offsets [PR96648]
PR analyzer/96648 reports an ICE within get_field_at_bit_offset due
to a negative bit offset, arising due to pointer arithmetic.
This patch replaces an assertion with handling for this case, fixing the
ICE.
gcc/analyzer/ChangeLog:
PR analyzer/96648
* region.cc (get_field_at_bit_offset): Gracefully handle negative
values for bit_offset.
gcc/testsuite/ChangeLog:
PR analyzer/96648
* gcc.dg/analyzer/pr96648.c: New test.
