This patch introduces a new option:
`-analyzer-disable-warning`
which could be used to disable warnings of given checkers.

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-disable-warning=core.DivideZero`.
