Implement some basic simplifications involving min/max, for example max(a,b) >= a -> true. According to my super-optimizer, these are by far the most common simplifications (of the -instsimplify kind) that occur in the testsuite and aren't caught by -std-compile-opts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130780 91177308-0d34-0410-b5e6-96231b3b80d8
