[DebugInfo] A value-tracking variable location update
...ving to track the location of a constant
that we already know.
* As mentioned in the "missing" variable locations list, gaps in lexical
scopes can lead to locations not being propagated sufficiently far, a
problem for both variable-location tracking solutions as documented in
PR48091. However, using DBG_VALUEs to track variable locations can save a
few of them because MachineSink can sink DBG_VALUEs over the scope gap,
wheras instruction-referencing tries to rely on tracking debug
use-before-defs which don't propagate across scope gaps. More on how to
resolve th...
