Please ignore this commit - this patch is for another bug fix,
although the testcase is the correct one.
I'll commit the testcase in a separate patch.
Sorry for the confusion.
Anyway, since this bug has been fixed by my earlier commit,
I'm marking it as fixed.

The testcase should go into the torture testsuite.

This is a bug in df-scan.c, marking regs unnecessarily as read-write,
which lead to unnecessarily stretched live ranges for regs involved in pre/post
modify insn. I'm working on it.
