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
