And restored missing error message from llvm-cov show
And since some CI builds disable LLVM assertions (which disables the
--debug option in llvm-cov show), I check to see if LLVM assertions are
disabled, and if so, I don't add --debug and don't check the counter
file diffs.

More portable way to make python 2/3 portable.
Strip Args line (with hardcoded paths) from debug counters output.
Ignore diff failures from llvm-cov debug output files ("counters"
files), since generic function instantiations will appear in those files
with mangled names. (Sadly, the demangler is apparently not applied to
the debug output.)

Implementing the Graph traits for the BasicCoverageBlock
graph.
optimized replacement of counters with expressions plus new BCB graphviz
* Avoid adding coverage to unreachable blocks.
* Special case for Goto at the end of the body. Make it non-reportable.
Improved debugging and formatting options (from env)
Don't automatically add counters to BCBs without CoverageSpans. They may
still get counters but only if there are dependencies from
other BCBs that have spans, I think.
Make CodeRegions optional for Counters too. It is
possible to inject counters (`llvm.instrprof.increment` intrinsic calls
without corresponding code regions in the coverage map. An expression
can still uses these counter values.
Refactored instrument_coverage.rs -> instrument_coverage/mod.rs, and
then broke up the mod into multiple files.
Compiling with coverage, with the expression optimization, works on
the json5format crate and its dependencies.
Refactored debug features from mod.rs to debug.rs
