Our internal integration relies on injecting some default values to
ignore/keep lists.
That means we can have filters, despite of not having occurences
for the flag.
We have a previous fix
be861b64d9,
which snapshots all processing files.
It works most of times, the snapshot (InMemoryFileSystem) is based on
the file path. The file-path-based lookup can fail in a subtle way for
some tricky cases (we encounter it internally), which will result in
reading a corrupted file.
This is a different fix, we don't modify files on the fly, instead, we
write files when the tool finishes for all files.
Snapshot all analysing files before running the tool, this makes sure
that we analyse all files statelessly and avoid the FileManager caching issue
when running `-edit` on multiple files.

The fixIncludes was using the `input` as the main file path, this will
results in inserting header at wrong places.
We need the main file path to so that we can get the real main-file
header.

If the source code is compilable-but-layering-violation, we still want
the tool to be functional on it (rather than bailing out).

The binary tool only works on working source code, if the source code is
not compilable, don't perform any analysis and edits.

This adds command-line flags to the tool:
+ -print: prints changed source code
+ -print=changes: prints headers added/removed
+ -edit: rewrites code in place
+ -insert=0/-remove=0: disables additions/deletions for the above
These are supported by a couple of new functions dumped into Analysis:
analyze() sits on top of walkUsed and makes used/unused decisions for
Includes. fixIncludes() applies those results to source code.

Header insertion doesn't actually work that well (not this patch's fault):
- we don't have ranking of locations/headers yet, so inserted header is pretty
random
- on my system, we get a lot of absolute "/usr/bin/../include/..." paths.
This is a HeaderSearch bug introduced in D60873 that I'll send a fix for

The immediate goal is to start producing an HTML report to debug and explain
include-cleaner recommendations.
For now, this includes only the lowest-level piece: a list of the references
found in the source code.
How this fits into future ideas:
- under refs we can also show the headers providing the symbol, which includes
match those headers etc
- we can also annotate the #include lines with which symbols they cover, and
add whichever includes we're suggesting too
- the include-cleaner tool will likely have modes where it emits diagnostics
and/or applies edits, so the HTML report is behind a flag
