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.

ASTMatchers currently have problems mixing bound TypeLoc nodes with Decl/Stmt
nodes. That should be fixed soon but for this checker there we only need the
TypeLoc to generate a fixit so postpone the potentially heavyweight AST walking
until after we know that we're going to emit a warning.
This is covered by existing test cases.
Original message:
[clang-tidy] Add a check for RAII temporaries.
This tries to find code similar that immediately destroys
an object that looks like it's trying to follow RAII.
{
scoped_lock(&global_mutex);
critical_section();
}
This checker will have false positives if someone uses this pattern
to legitimately invoke a destructor immediately (or the statement is
at the end of a scope anyway). To reduce the number we ignore this
pattern in macros (this is heavily used by gtest) and ignore objects
with no user-defined destructor.
