[llvm-dwarfdump][Statistics] Change the coverage buckets representation. NFC

Browse Source 
Summary:
This changes the representation of 'coverage buckets' in llvm-dwarfdump and
llvm-locstats to one that makes more clear what the buckets contain.

See some related details in D71070.

The line 0% shows the number and the percentage of DIEs with no location
information, but the line 100% shows the information for DIEs where there is
location information in all code section bytes (where the variable or parameter
is in the scope). The line 50-59% shows the number and the percentage of DIEs
where the location information is between 50 and 59 percentage of its scope
is in the scope). The line [50%,60%) shows the number and the percentage of DIEs
where the location information is between 50 and 60 percentage of its scope
covered.
