Cameron Zwarich [Wed, 12 Oct 2011 21:24:54 +0000 (21:24 +0000)]
To find the exiting VN of a LiveInterval from a block, use the previous slot
rather than the previous index. If a block has a single instruction, the
previous index may be in a different basic block.

I have no clue how this used to work on all of test-suite, because now this
failure is seen quite often when trying to compile code with -strong-phi-elim.
This fixes PR10252.
