c++: support target attr for DECL_LOCAL_DECL_P fns [PR99108]
We crash when target attribute get_function_versions_dispatcher is called
for a function that is not registered in call graph. This was happening
because we were calling it for the function-local decls that aren't in the
symbol table, instead of the corresponding namespace-scope decls that are.
gcc/cp/ChangeLog:
PR c++/99108
* call.c (get_function_version_dispatcher): Handle
DECL_LOCAL_DECL_P.
* decl.c (maybe_version_functions): Likewise.
(maybe_mark_function_versioned): New.
* name-lookup.c (push_local_extern_decl_alias): No longer static.
* name-lookup.h (push_local_extern_decl_alias): Adjust.
gcc/testsuite/ChangeLog:
PR c++/99108
* g++.target/i386/pr99108.C: New test.
