X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same
instruction, we only want to allow the one for the current subtarget. - This also fixes suffix matching for jmp instructions, because it eliminates the ambiguity between 'jmpl' and 'jmpq'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108746 91177308-0d34-0410-b5e6-96231b3b80d8
