9a211fe7 - [TableGen] Fix concatenation of subreg and artificial subregs (#114391)

[TableGen] Fix concatenation of subreg and artificial subregs (#114391) When CoveredBySubRegs is true and a sub-register consists of two parts; a regular subreg and an artificial subreg, then TableGen should consider only concatenating the non-artificial subregs. For example, S0_S1 is a concatenated subreg from D0_D1, but S0_S1_HI should not be considered.
