HAIFA scheduler bug?

[Jim Wilson]

	Actually we made some changes to reduce the change that jump will bogusly
	use a REG_DEAD note after reload.  I suspect we didn't catch all of
	them, but we may have caught the one in question.

What changes exactly are these?  I can't see anything obvious looking at
the ChangeLog file.

There haven't been any changes at all to delete_computation which is where
the bug is.  It is still using REG_DEAD notes which are obviously unsafe.
It happens to work by accident for the testcase, but the original bug report
points out that the current sources still fail to compile makeinfo correctly
so there is still a bug present that needs to be fixed.
