Alp Toker ca70f4fa1c ExpectAndConsume: Diagnose errors automatically
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.

diagnostics.

Alp Toker af9a02c0cd Support and use token kinds as diagnostic arguments
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.

Richard Smith 8a88a0b715 Generate a marker token when entering or leaving a submodule when building a
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).

Argyrios Kyrtzidis ab2d09b628 [Parser] Don't code-complete twice.
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.

Richard Smith 3a2b7a18a4 Finish semantic analysis for [[carries_dependency]] attribute.
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).

Nico Weber b707a4762f Don't require a space between the two ">" in "vector<id<protocol>>" in objc++11.
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,
and improves the diagnostic in c++98 mode.

Chandler Carruth 55fc873017 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

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.
