This reverts commitcf1c774d6a. This change caused several regressions in the gdb test suite - at least a sample of which was due to line zero instructions making breakpoints un-lined. I think they're worth investigating/understanding more (& possibly addressing) before moving forward with this change. Revert "[FastISel] NFC: Clean up unnecessary bookkeeping" This reverts commit3fd39d3694. Revert "[FastISel] NFC: Remove obsolete -fast-isel-sink-local-values option" This reverts commita474657e30. Revert "Remove static function unused after cf1c774." This reverts commitdc35368ccf. Revert "[lldb] Fix TestThreadStepOut.py after "Flush local value map on every instruction"" This reverts commit53a14a47ee.
