Richard Smith 3be1cb294f Use -Rblah, not -Wblah, to control remark diagnostics. This was always the 
intent when we added remark support, but was never implemented in the general
case, because the first -R flags didn't need it. (-Rpass= had special handling
to accomodate its argument.)

-Rno-foo, -Reverything, and -Rno-everything can be used to turn off a remark,
or to turn on or off all remarks. Per discussion on cfe-commits, -Weverything
does not affect remarks, and -Reverything does not affect warnings or errors.

The only "real" -R flag we have right now is -Rmodule-build; that flag is
effectively renamed from -Wmodule-build to -Rmodule-build by this change.

-Wpass and -Wno-pass (and their friends) are also renamed to -Rpass and
-Rno-pass by this change; it's not completely clear whether we intended to have
a -Rpass (with no =pattern), but that is unchanged by this commit, other than
the flag name. The default pattern is effectively one which matches no passes.
In future, we may want to make the default pattern be .*, so that -Reverything
works for -Rpass properly.

Alp Toker 46df1c0db8 Complete the switch from mappings to declarative diagnostic severities 
This begins to address cognitive dissonance caused by treating the Note
diagnostic level as a severity in the diagnostic engine.

No change in functionality.

Alp Toker c726c367f4 Improve diagnostic mapping terminology 
Diagnostic mappings are used to calculate the final severity of diagnostic
instances.

Detangle the implementation to reflect the terminology used in documentation
and bindings.

No change in functionality.

Ben Langmuir b92de02f17 Reapply r207477 and r207479 without cyclic dependency 
Fixed by moving ProcessWarningOptions from Frontend into Basic. All of
the dependencies for ProcessWarningOptions were already in Basic, so
this was a small change.
