c: Ignore _Atomic on function return type for C2x
For C2x it was decided that _Atomic would be completely ignored on
function return types (just as was done for qualifiers in C11 DR#423),
to eliminate the potential for an rvalue returned by a function having
_Atomic-qualified type when an rvalue resulting from lvalue-to-rvalue
conversion could not have such a type. Implement this for GCC.
Bootstrapped with no regressions for x86_64-pc-linux-gnu.
gcc/c/
* c-decl.cc (grokdeclarator): Ignore _Atomic on function return
type for C2x.
gcc/testsuite/
* gcc.dg/qual-return-9.c, gcc.dg/qual-return-10.c: New tests.
