[TableGen] Speed up inferMatchingSuperRegClass. NFC. (#133060)
SubToSuperRegs was a DenseMap of std::vectors, where the vectors
typically had size 1. Switching to a vector of pairs avoids the overhead
of allocating tiny vectors.
I measured a 1.14x speed-up building AMDGPUGenRegisterInfo.inc with this
patch.
