Otherwise we will emit 'unavailable' errors when referencing an unavailable super class

in debugger mode) to accept @import declarations
and pass them to the debugger.
In the preprocessor, accept import declarations
if the debugger is enabled, but don't actually
load the module, just pass the import path on to
the preprocessor callbacks.
In the Objective-C parser, if it sees an import
declaration in statement context (usual for LLDB),
ignore it and return a NullStmt.

Among other things, this allows recovery in several cases where it
wasn't possible before (e.g. correcting a mistyped static_cast<>).

than one method with mismatched type of same selector name.
clang issues a warning to point this out since it may cause
undefined behavior. There are cases though that some APIs
don't care about user methods and such warnings are perceived as
noise. This patch allows users to add paren delimiters around
selector name to turn off such warnings. So, @selector((save:)) will
turn off the warning. It also provides 'fixit' so user knows
what to do. // rdar://16458579

1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
using the generic diagnostic descriptions added in r197972, eliminating another
set of trivial err_expected_* variations while maintaining existing behaviour.
2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
family of functions are primitive parser operations that now have the
well-defined property of operating on single tokens. Factoring out recovery
exposes opportunities for more consistent and tailored error recover at the
call sites instead of just relying on a bottled SkipUntil formula.

Introduce proper facilities to render token spellings using the diagnostic
formatter.
Replaces most of the hard-coded diagnostic messages related to expected tokens,
which all shared the same semantics but had to be multiply defined due to
variations in token order or quote marks.
The associated parser changes are largely mechanical but they expose
commonality in whole chunks of the parser that can now be factored away.
This commit uses C++11 typed enums along with a speculative legacy fallback
until the transition is complete.
Requires corresponding changes in LLVM r197895.

module. Use the marker to diagnose cases where we try to transition between
submodules when not at the top level (most likely because a closing brace was
missing at the end of a header file, but is also possible if submodule headers
attempt to do something fundamentally non-modular, like our .def files).

When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.
Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.
Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

This required plumbing through a new flag to determine whether a ParmVarDecl is
actually a parameter of a function declaration (as opposed to a function
typedef etc, where the attribute is prohibited). Weirdly, this attribute (just
like [[noreturn]]) cannot be applied to a function type, just to a function
declaration (and its parameters).

C++11 allowed writing "vector<vector<int>>" without a space between the two ">".
This change allows this for protocols in template lists too in -std=c++11 mode,

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.
