ART: Checker tests for --debuggable

Checker was disabled for --debuggable because the code was not compiled
with Optimizing. Now that it is, we might want to write Checker tests
only for this mode. With this patch, CHECK-START(-ARCH)-DEBUGGABLE
tests will only be invoked on output of debuggable compilation.
Existing CHECK-START(-ARCH) tests will not be invoked.
