The LiveDebugValues pass recognizes spills but not restores, which can cause large gaps in location information for some variables, depending on control flow. This patch make LiveDebugValues recognize restores and generate appropriate DBG_VALUE instructions. This patch was posted previously with r352642 and reverted in r352666 due to buildbot errors. A missing return statement was the cause for the failures.
