Sanjay Patel c7b58da814 [x86] machine combiner reassociation: mark EFLAGS operand as 'dead' 
In the commentary for D11660, I wasn't sure if it was alright to create new
integer machine instructions without also creating the implicit EFLAGS operand. 
From what I can see, the implicit operand is always created by the MachineInstrBuilder
based on the instruction type, so we don't have to do that explicitly. However, in
reviewing the debug output, I noticed that the operand was not marked as 'dead'. 
The machine combiner should do that to preserve future optimization opportunities 
that may be checking for that dead EFLAGS operand themselves.
