Duncan Sands fc33df78c1 Improve threading of comparisons over select instructions (spotted by my ... auto-simplifier). This has a big impact on Ada code, but not much else. Unfortunately the impact is mostly negative! This is due to PR9004 (aka SCCP failing to resolve conditional branch conditions in the destination blocks of the branch), in which simple correlated expressions are not resolved but complicated ones are, so simplifying has a bad effect! llvm-svn: 124788		2011-02-03 09:37:39 +00:00
