gcc46-pr45663.patch

A sign extension insn for the first bar call is scheduled before the a.j++
insns
with the debug_insn for a$j.  While at the call itself the vars already have
expected values, at the first insn on the same line as the first bar call (the
sign extension) a.j is still 13, not 14.

I think we could fix this up by adjusting the testcase (with current trunk it
gives no failures on both x86_64-linux and i686-linux), though haven't tested
other targets.

Not sure I understand everything involved here, but isn't the test a little
suspect any time higher optimization levels and instruction scheduling are
enabled?
