Varible Scope info is being disabled. Variable
Live Range is being enabled. Debug info generated
for debug code is the same, changes only impact on
optimized code.

Variable Live Range updates variable's location
each time something happens to variable's
liveness. For more information see
https://github.com/dotnet/runtime/blob/master/docs/design/features/variabletracking.md

When a variable is being born at the same location it
died at the previous assembly instruction (in the same
group of instructions), we reported as it was alive
the whole time.
