Don't run -Wunreachable-code on template instantiations.  Different instantiations may produce different unreachable code results, and it is very difficult for us to prove that ALL instantiations of a template have specific unreachable code.  If we come up with a better solution, then we can revisit this, but this approach will at least greatly reduce the noise of this warning for code that makes use of templates.

callback client to suggest an alternative search path and after we
complain when the included file can't be found. The former can't be
tested in isolation, the latter doesn't actually matter (because we
won't make a module suggestion if no header is available). However,
the flow is better this way.

when dealing with submodules. For now, we only use it to ensure that
the module "key" returned when loading a module will always be a
module (rather than occasionally being a FileEntry).

really bad way to go about this, but I'm not sure there's a better
choice without substantial changes to TreeTransform --- most
notably, preserving implicit semantic nodes instead of discarding
and rebuilding them.

check whether the named submodules themselves are actually
valid, and drill down to the named submodule (although we don't do
anything with it yet). Perform typo correction on the submodule names
when possible.

The new metadata are method @encode strings with additional data.

1. Each Objective-C object is marked with its class name and protocol names.
The same is done for property @encode already.

2. Each block object is marked with its function prototype's @encoding. For
example, a method parameter that is a block object that itself returns void
and takes an int would look like:
    @?<v@?i>

These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.

Relax RegionStore to allow loads from CodeTextRegions.  Apparently you can actually write code that does this.  This seems worthy of a checker, but the StoreManager should handle the memory abstraction without crashing.  Fixes PR 11450.
