C: don't suggest names that came from earlier failures (PR c/83056)
PR c/83056 reports an issue affecting trunk and gcc-7 in which
the C frontend's implementation of lookup_name_fuzzy uses undeclared
identifiers as suggestions when encountering subsequent undeclared
identifiers.
The fix is to filter out the names bound to error_mark_node
in lookup_name_fuzzy.
The C++ frontend is unaffected, as it already does this.
gcc/c/ChangeLog:
PR c/83056
* c-decl.c (lookup_name_fuzzy): Don't suggest names that came from
earlier failed lookups.
gcc/testsuite/ChangeLog:
PR c/83056
* gcc.dg/spellcheck-pr83056.c: New test case.
