gas simple-forward test

Tests that target md_apply_fix can handle fixups that have resolved
down to a constant and thus do not need relocations.

Also a fix for eqv-dot xfails.

	* testsuite/gas/all/simple-forward.d,
	* testsuite/gas/all/simple-forward.s: New test.
	* testsuite/gas/all/gas.exp: Run it.
	* testsuite/gas/all/eqv-dot.d: xfail tic30 and tic54x.
