[committed][testsuite] Add scan-offload-rtl-dump


Hi,

This patch adds scan-offload-rtl-dump, similar to scan-offload-tree-dump.

Build and reg-tested on x86_64 with nvptx accelerator.

Pre-approved here ( https://gcc.gnu.org/ml/gcc-patches/2018-05/msg01089.html ).

Committed to trunk.

Thanks,
- Tom

	* gcc.dg-selftests/dg-final.exp (dg_final_directive_check_num_args): Add
	offload-rtl.

	* doc/sourcebuild.texi (Commands for use in dg-final, Scan optimization
	dump files): Add offload-rtl.
