[analyzer] Analysis: Silence checkers
This patch introduces a new analyzer-config configuration:
which could be used to silence the given checkers.
It accepts a semicolon separated list, packed into quotation marks, e.g:
It could be used to "disable" core checkers, so they model the analysis as
before, just if some of them are too noisy it prevents to emit reports.
This patch also adds support for that new option to the scan-build.
Passing the option -disable-checker core.DivideZero to the scan-build
will be transferred to -analyzer-config silence-checkers=core.DivideZero.
