[committed] Fix C++ ICE with UDRs (PR c++/58874)

[Jakub Jelinek]

Hi!

The problem on this testcase was that
start_preparsed_function called maybe_begin_member_template_processing
but finish_function wasn't called with matching flag and thus
didn't call maybe_end_member_template_processing and we ended up with
processing_template_decl even when it shouldn't be set.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk.

	PR c++/58874
	* parser.c (cp_parser_late_parsing_for_member): For OpenMP UDRs
	pass 2 instead of 0 to finish_function.

	* g++.dg/gomp/pr58874.C: New test.
