Further testcase simplification
The third testcase uses only "rm" and "=&rm" constraints, which means that it
might not be specific to i386 targets. I still have to try other targets.
Note that the bug only occurs if there are sufficiently many registers in the
clobber list (otherwise the compiler just uses registers for everything).
