With the changes introduced in D86151 <https://reviews.llvm.org/D86151> we can now easily check for single locations
which span multiple blocks for inlined scopes and blocks.

CTMark shows a geomean binary size reduction of 2.2% for RelWithDebInfo builds.
llvm-locstats (using D85636 <https://reviews.llvm.org/D85636>) shows a very small variable location coverage
change in 5 of 10 binaries, but just like in D86151 <https://reviews.llvm.org/D86151> it is only in the order of
10s of bytes.
