analyzer: fix ICE with fortran constant arguments (PR 93405)
PR analyzer/93405 reports an ICE with -fanalyzer when passing
a constant "by reference" in gfortran.
The issue is that the constant is passed as an ADDR_EXPR
of a CONST_DECL, and region_model::get_lvalue_1 doesn't
know how to handle CONST_DECL.
This patch implements it for CONST_DECL by providing
a placeholder region, holding the CONST_DECL's value,
fixing the ICE.
gcc/analyzer/ChangeLog:
PR analyzer/93405
* region-model.cc (region_model::get_lvalue_1): Implement
CONST_DECL.
gcc/testsuite/ChangeLog:
PR analyzer/93405
* gfortran.dg/analyzer/pr93405.f90: New test.
