BR 3392260: Handle instructions only separated by vector SIB size
There are two instructions (VGATHERQPS, VPGATHERQD) where the only
separation between two forms is the vector length given to the vector
SIB. This means the *matcher* has to be able to distinguish
instructions by vector SIB length and the matcher only operates on the
operands and the instruction flags, not on the bytecode.
Export the vector index-ness into the operand flags and add to the
matcher.
This resolves BR 3392260.
