configures it's own pipeline.

named physical register with named vregs.

It appears that we haven't been prioritizing rules that contain nested
instructions properly. InstructionOperandMatcher didn't override
isHigherPriorityThan so it never compared the instructions/operands/predicates
inside nested instructions.
Fixes PR35926. Thanks to Diana Picus for the bug report.
