Jakob Stoklund Olesen a36fe73645 Add an analyzeVirtReg() function. 
This function does more or less the same as
MI::readsWritesVirtualRegister(), but it supports bundles as well.

It also determines if any constraint requires reading and writing
operands to use the same register.  Most clients want to know.

Use the more modern MO.readsReg() instead of trying to sort out undefs
and partial redefines.  Stop supporting the extra full <imp-def> operand
as an alternative to <def,undef> sub-register defines.
