Ben Barham fbb499ef25 [AST] Fix crashes caused by redeclarations in hidden prototypes
ObjCContainerDecl.getMethod returns a nullptr by default when the
container is a hidden prototype. Callsites where the method is being
looked up on the redeclaration's own container should skip this check
since they (rightly) expect a valid method to be found.

Ben Langmuir 6d25fdc41b [Modules] Don't infinite recurse on implicit import of circular modules in preamble
Update the Preprocessor's VisibleModuleSet when typo-correction creates
an implicit module import so that we won't accidentally write an invalid
SourceLocation into the preamble AST.  This would later lead to infinite
recursion when loading the preamble AST because we use the value in
ImportLocs to prevent visiting a module twice.

Ben Langmuir c28ce3aba6 Avoid a crash after loading an #undef'd macro in code completion
In code-completion, don't assume there is a MacroInfo for everything,
since we aren't serializing the def corresponding to a later #undef in
the same module.  Also setup the HadMacro bit correctly for undefs to
avoid an assertion failure.

Ben Langmuir 8832c066a2 Honour -ivfsoverlay in ASTUnit to match clang
This allows code indexing, etc. to use the VFS in the same way as the
compiler.
