[PATCH] D27457: [globalisel] Tablegen-erate PartialMapping*/ValueMapping*/BankIDToCopyMapIdx.

dsanders added a dependency: D27339: [globalisel][aarch64] Make getCopyMapping() take register banks ID's rather than IsGPR booleans.
Herald added subscribers: rovka, dberris, vkalintiris.

Note that the order of register banks in the tables swaps as a result. This has
no effect on behaviour because of the fixes in r288812. Also, a couple fields
are not controllable from the .td files because there's no variety in the
current values (NumBreakDowns of RegisterBankInfo::ValueMapping is always 1,
and StartIdx of RegisterBankInfo::PartialMapping, is always 0).

Depends on https://reviews.llvm.org/D27339
