[c] Fix PR 101364: ICE after error due to diagnose_arglist_conflict not checking for error
When checking to see if we have a function declaration has a conflict due to
promotations, there is no test to see if the type was an error mark and then calls
c_type_promotes_to. c_type_promotes_to is not ready for error_mark and causes an
ICE.
This adds a check for error before the call of c_type_promotes_to.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR c/101364
gcc/c/ChangeLog:
* c-decl.cc (diagnose_arglist_conflict): Test for
error mark before calling of c_type_promotes_to.
gcc/testsuite/ChangeLog:
* gcc.dg/pr101364-1.c: New test.
