This series makes the PowerPC port deal with the {add,subf}{c,ic,e,ze,me}
instructions directly, not as bigger primitives (which used to be emitted as
multiple machine instructions).It does this by expanding multi-precision add/sub/neg as well as the unsigned wordlength sCOND to separate machine insns, which are then simplified where possible by the combine pass and friends. For eq/ne this series splits after combine. This is PR target/64180. All patches bootstrapped and tested on powerpc64-linux, runtestflags -m32,-m64,-m32/-mpowerpc64,-m64/-mlra; also a lot of tiny tests that I'll submit separately. Comments? Is this okay for mainline?
