Summary: D11924 implemented part of the floating-point comparisons, this patch implements the rest: * Tell ISelLowering that all booleans are either 0 or 1. * Expand the eq/ne/lt/le/gt/ge floating-point comparisons to the canonical ones (similar to what Mips32r6InstrInfo.td does). * Add tests for ord/uno. * Add tests for ueq/one/ult/ule/ugt/uge. * Fix existing comparison tests to remove the (res & 1) code, which setBooleanContents stops from generating.
