[PATCH] D29835: Correct register pressure calculation in presence of subregs

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 89245.
rampitec added a comment.

Added callback for a target to estimate register unit weight given a lane mask, since that is unclear if proportional weight is correct for all targets.
