Log:
fix a crash on:

let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {

we now get:

X86InstrCompiler.td:653:52: error: Expected class, def, defm, multiclass or let definition
let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {
                                                   ^
