analyzer: fix ICE on unhandled tree codes in get_rvalue_1 [PR96641]
The old implementation of region_model::get_rvalue_1 gracefully handled
tree codes it didn't understand, returning "UNKNOWN", whereas the new
implementation (r11-2694-g808f4dfeb3a95f50f15e71148e5c1067f90a126d) had
an assertion left over from development, leading to ICEs.
This patch restores the old behavior for these cases.
gcc/analyzer/ChangeLog:
PR analyzer/96641
* region-model.cc (region_model::get_rvalue_1): Handle
unrecognized tree codes by returning "UNKNOWN.
gcc/testsuite/ChangeLog:

* g++.dg/analyzer/pr96641.C: New test.
