[x86] NFC: Clean up two tests and generate precise checks for them. Mostly this involved giving unnamed values names and running the IR through `opt` to re-format it but merging in any important comments in the original. I then deleted pointless comments and inlined the function attributes for ease of reading and editting. All of this is to make it much easier to see the instructions being generated here and evaluate any updates to the tests. llvm-svn: 311634
