c: Fix tagname confusion for typedef redefinitions [PR118765]
When we redefine a typedef for a tagged type that has just been
redefined, merge_decls may produce invalid TYPE_DECLS that are not
consistent with what set_underlying_type produces. This is fixed
by updating DECL_ORIGINAL_TYPE.
PR c/118765
gcc/c/ChangeLog:
* c-decl.cc (merge_decls): For TYPE_DECLS copy
DECL_ORIGINAL_TYPE from the old declaration.
* c-typeck.cc (tagged_types_tu_compatible_p): Add
checking assertions.
gcc/testsuite/ChangeLog:
* gcc.dg/pr118765-2.c: New test.
* gcc.dg/pr118765-3.c: New test.
* gcc.dg/typedef-redecl3.c: New test.
