Enforce stricter rules in machine code verifier. Implicit operands no longer get a free pass: Imp-use requires a live register and imp-def requires a dead register. There is also no special rule allowing redefinition of a sub-register when the super-register is live. The super register must have imp-kill+imp-def operands instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78090 91177308-0d34-0410-b5e6-96231b3b80d8
