Ensure DynFlags are consistent
While we have always had makeDynFlagsConsistent to enforce a variety of
consistency invariants on DynFlags, it hasn't been widely used.
GHC.Main, for instance, ignored it entirely. This leads to issues like
Trac #10549, where an OPTIONS_GHC pragma introduced an inconsistency,
leading to a perplexing crash later in compilation.
Here I add consistency checks in GHC.Main.set{Session,Program}DynFlags,
closing this hole.
Fixes #10549.
Test Plan: Validate with T10549
