OpenMP: testsuite fixups for C++ allocators

The patch "OpenMP: Add C++ support for 'omp allocate'" is a backport
of a mainline patch.  These additional testsuite fixes are necessary to
shut up bogus failures on OG15 but maybe are not required or suitable for
upstream.

gcc/testsuite/
	* c-c++-common/gomp/uses_allocators-1.c: Adjust for this testcase
	no longer failing with "sorry" in C++.
	* g++.dg/gomp/allocate-15.C: Disable scan-assembler tests since
	compilation fails with "sorry" before getting that far.
	* g++.dg/gomp/allocate-16.C: Likewise.
