This hints the operand of a t2DoLoopStart towards using LR, which can help make it more likely to become t2DLS lr, lr. This makes it easier to move if needed (as the input is the same as the output), or potentially remove entirely. The hint is added after others (from COPY's etc) which still take precedence. It needed to find a place to add the hint, which currently uses the post isel custom inserter. Differential Revision: https://reviews.llvm.org/D89883
