[PATCH] D19353: [GVN] Replace an inverted comparison with a logical not

[Geoff Berry via llvm-commits]

@reames I believe CodeGenPrepare::SinkCmpExpressions already takes care of this.

@mcrosier I would guess that any cond branches that have not(c) as their condition would get simplified to use just 'c' and swap the branch targets, so I don't think this would impact the optimizations you mentioned.
