[PATCH] analyzer: fix ICE on METHOD_TYPE (PR 93212)

[David Malcolm]

PR analyzer/93212 reports an ICE when attempting to use -fanalyzer
on a C++ source file.  That isn't supported yet, but the fix is
trivial (handling METHOD_TYPE as well as FUNCTION_TYPE).

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to the dmalcolm/analyzer branch on the GCC git mirror.

gcc/analyzer/ChangeLog:
        PR analyzer/93212
        * region-model.cc (make_region_for_type): Use
        FUNC_OR_METHOD_TYPE_P rather than comparing against FUNCTION_TYPE.
        * region-model.h (function_region::function_region): Likewise.
