bmeurer@chromium.org e0e17b905d Revert "[arm] Shorter test names for parameterized tests." 
This reverts commit r23142 because GoogleTest is very picky about the
parameterized test case names, so not even using an anonymous namespace
can please GTest. Also reverts the renaming applied to in the
ChangeLowering unit test.
