MC/X86: Subdivide immediates a bit more, so that we properly recognize immediates based on the width of the target instruction. For example: addw $0xFFFF, %ax should match the same as addw $-1, %ax but we used to match it to the longer encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104453 91177308-0d34-0410-b5e6-96231b3b80d8

Replace a gross hack (the MOV64ri_alt instruction) with a slightly less gross hack (having the asmmatcher handle the alias). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115685 91177308-0d34-0410-b5e6-96231b3b80d8
