Without the fix ivars with anonymous types can trigger errors like
> error: 'TestClass::structIvar' from module 'Target' is not present in definition of 'TestClass' provided earlier
> [...]
> note: declaration of 'structIvar' does not match
It happens because types of ivars from different modules are considered
to be different. And it is caused by not merging anonymous `TagDecl`
from different modules.
To fix that I've changed `serialization::needsAnonymousDeclarationNumber`
to handle anonymous `TagDecl` inside `ObjCInterfaceDecl`. But that's not
sufficient as C code inside `ObjCInterfaceDecl` doesn't use interface
decl as a decl context but switches to its parent (TranslationUnit in
most cases). I'm changing that to make `ObjCContainerDecl` the lexical
decl context but keeping the semantic decl context intact.
Test "check-dup-decls-inside-objc.m" doesn't reflect a change in
functionality but captures the existing behavior to prevent regressions.

Windows member functions have __attribute__((thiscall)) on their type,
so any machine running this that is 32 bit windows fails this test, add
a wildcard, plus an additional run line to explain why.
After rGa9db0a804a53, we correctly determined the end for pointer types
like `id` that are spelled without a `*`, but incorrectly determined the
end for pointer types spelled with a `*`.
The outputs between the direct ast-dump test and the ast-dump test after
deserialization should match modulo a few differences.
For hand-written tests, strip the "<undeserialized declarations>"s and
the "imported"s with sed.
For tests generated with "make-ast-dump-check.sh", regenerate the
output.
Part 2/n.
Summary:
Removal of the child node makes it easier to separate traversal from
output generation.

This moves everything primarily testing the functionality of -ast-dump and -ast-print into their own directory, rather than leaving the tests spread around the testing directory.
