Chris Lattner d2191e549b Add a fastpath to Load GVN to special case when we have exactly one dominating ... load to avoid even messing around with SSAUpdate at all. In this case (which is very common, we can just use the input value directly). This speeds up GVN time on gcc.c-torture/20001226-1.c from 36.4s to 16.3s, which still isn't great, but substantially better and this is a simple speedup that applies to lots of different cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91851 91177308-0d34-0410-b5e6-96231b3b80d8		2009-12-21 23:15:48 +00:00
