[PATCH] [og9] Add omp_pause_resource{,_all} for AMD GCN

[Julian Brown <julian@codesourcery.com>]

This patch adds some missing functions to the AMD GCN-specific target.c
file. This fixes several link errors in the testsuite.

Tested with offloading to AMD GCN. I will apply to the
openacc-gcc-9-branch shortly.
