[utils] Implement the llvm-locstats tool
The tool reports verbose output for the DWARF debug location coverage.
The llvm-locstats for each variable or formal parameter DIE computes
what percentage from the code section bytes, where it is in scope, it
has location description. The line 0 shows the number (and the
percentage) of DIEs with no location information, but the line 100 shows
the number (and the percentage) of 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 in between 50 and 59
percentage of its scope covered.
The tool will be very useful for tracking improvements regarding the
"debugging optimized code" support with LLVM ecosystem.
