Jakob Stoklund Olesen d37bc5a27b 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.
