[PATCH] D32114: [APInt] Merge the multiword code from lshrInPlace and tcShiftRight into a single implementation

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

This merges the two different multiword shift right implementations into a single version located in tcShiftRight. lshrInPlace now calls tcShiftRight for the multiword case.

I retained the memmove fast path from lshrInPlace and used a memset for the zeroing. The for loop is basically tcShiftRight's implementation with the zeroing and the intra-shift of 0 removed.
