Summary:
Each check can implement readOptions and storeOptions methods to read
and store custom options. Each check's options are stored in a local namespace
to avoid name collisions and provide some sort of context to the user.

This checks that parameters named in comments that appear before arguments in
function and constructor calls match the parameter name used in the callee's
declaration. For example:
void f(int x, int y);
void g() {
f(/*y=*/0, /*z=*/0);
}
contains two violations of the policy, as the names 'x' and 'y' used in the
declaration do not match names 'y' and 'z' used at the call site.
I think there is significant value in being able to check/enforce this policy
as a way of guarding against accidental API misuse and silent breakages
caused by API changes.
Although this pattern appears somewhat frequently in the LLVM codebase,
this policy is not prescribed by the LLVM coding standards at the moment,
so it lives under 'misc'.
