This fixes minor issues in the recently added tests for 71947.

First in two tests we use an x86 opcode.  We don't actually assemble the 
tests, so it really doesn't matter, but just to make it clear the test 
is not x86 specific, the opcode was changed to "xyzzy" :-)

One test is dependent on branch costing.  So it's been changed to an 
opt-in test.

Installed on the trunk.
