Jakob Stoklund Olesen b81cbc271f Compute topological signatures of registers. ...

TableGen creates new register classes and sub-register indices based on
the sub-register structure present in the register bank. So far, it has
been doing that on a per-register basis, but that is not very efficient.

This patch teaches TableGen to compute topological signatures for
registers, and use that to reduce the amount of redundant computation.
Registers get the same TopoSig if they have identical sub-register
structure.

TopoSigs are not currently exposed outside TableGen.
