[PATCH] D15815: [SLP] Truncate expressions to minimum required bit width

[Matthew Simpson via llvm-commits]

Hi Nadav. Yes, I measured compile-time and performance of this patch together with http://reviews.llvm.org/D14829 (I included the results in comments for that revision). There were no compile-time regressions and modest performance improvements in two spec benchmarks (povray and h264ref). But I've temporarily reverted this patch due to a failing bot while I correct the issue.
