Stephen Tozer 36af7345df Reapply "[Clang] Enable -fextend-variable-liveness at -Og (#118026)" ...

Relands this feature after several fixes:

* Force fake uses to be emitted before musttail calls (#136867)
* Added soften-float legalization for fake uses (#142714)
* Treat fake uses as size-less instructions in a SystemZ assert (#144390)

If further issues with fake uses are found then this may be reverted again,
but all currently-known issues are resolved.

This reverts commit 2dc6e98169.
