c++: constrained surrogate call functions [PR110535]
We weren't checking constraints on pointer/reference-to-function conversion
functions during overload resolution, which caused us to ICE on the first
testcase and reject the second testcase.
PR c++/110535
gcc/cp/ChangeLog:
* call.cc (add_conv_candidate): Check constraints.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/concepts-surrogate1.C: New test.
* g++.dg/cpp2a/concepts-surrogate2.C: New test.
