Craig Topper 1dc8fc8bfa [APInt] Add compare/compareSigned methods that return -1, 0, 1. Reimplement slt/ult and friends using them ... Currently sle and ule have to call slt/ult and eq to get the proper answer. This results in extra code for both calls and additional scans of multiword APInts. This patch replaces slt/ult with a compareSigned/compare that can return -1, 0, or 1 so we can cover all the comparison functions with a single call. While I was there I removed the activeBits calls and other checks at the start of the slow part of ult. Both of the activeBits calls potentially scan through each of the APInts separately. I can't imagine that's any better than just scanning them in parallel and doing the compares. Now we just share the code with tcCompare. These changes seem to be good for about a 7-8k reduction on the size of the opt binary on my local x86-64 build.
