  [LiveDebugVariables] Stop trimming locations of non-inlined vars

The D35953, D62650 and D73691 introduced trimming of variables locations
in LiveDebugVariables pass, since there are some cases where after
the virtregrewrite we have exploded number of DBG_VALUEs created for some
inlined variables. As it looks, all problematic cases were regarding
inlined variables, so it seems reasonable to stop trimming the location
ranges for non-inlined variables.
It has very good impact on the llvm-locstats report.
