  Revert "[FastISel] Flush local value map on ever instruction" and dependent patches

This reverts commit cf1c774d6ace59c5adc9ab71b31e762c1be695b1.

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 commit 3fd39d3694d32efa44242c099e923a7f4d982095.

Revert "[FastISel] NFC: Remove obsolete -fast-isel-sink-local-values option"
This reverts commit a474657e30edccd9e175d92bddeefcfa544751b2.

Revert "Remove static function unused after cf1c774."
This reverts commit dc35368ccf17a7dca0874ace7490cc3836fb063f.

Revert "[lldb] Fix TestThreadStepOut.py after "Flush local value map on every instruction""
This reverts commit 53a14a47ee89dadb8798ca8ed19848f33f4551d5.
