InstrProf: Use the proftext format for these coverage tests This format's easier to understand and update by hand. llvm-svn: 231686

llvm-cov: add code coverage tool that's based on coverage mapping format and clang's pgo. This commit expands llvm-cov's functionality by adding support for a new code coverage tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling. The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument, or by modifying the tool's name to end with 'gcov'.

InstrProf: Fix display of large numbers in llvm-cov llvm-cov was truncating numbers that were larger than a particular fixed width, which is as confusing as it is useless. Instead, we use engineering notation with SI prefix for magnitude. llvm-svn: 237307

[llvm-cov] Create an index of reports in -output-dir mode This index lists the reports available in the 'coverage' sub-directory. This will help navigate coverage output from large projects.
