[TableGen] Fix invalid comparison function `SizeOrder` in `getMatchingSubClassWithSubRegs` 

Building LLVM with -DEXPENSIVE_CHECKS fails with the following error
message with libstdc++ in debug mode:

Error: comparison doesn't meet irreflexive requirements,
assert(!(a < a)).

The patch fixes the comparison function SizeOrder by returning false
when comparing two equal items.
