c++: non-standalone surrogate call template

I noticed we're accidentally prevented from considering a pointer- or
reference-to-function conversion function template if it's not the first
conversion function that's considered, which for the testcase below
results in us accepting the B call but not the A call despite the only
difference between A and B being their order of member declarations.
This patch fixes this so that the outcome of overload resolution doesn't
arbitrarily depend on declaration order here.

gcc/cp/ChangeLog:

	* call.cc (add_template_conv_candidate): Don't check for
	non-empty 'candidates' here.
	(build_op_call): Check it here, before we've considered any
	conversion functions.

gcc/testsuite/ChangeLog:

	* g++.dg/overload/conv-op5.C: New test.
