453b012513 Make sure to always check the result of 
SourceManager::getPresumedLoc(), so that we don't try to make use of
an invalid presumed location. Doing so can cause crashes.

f71b45367f Document Clang's support for attributes on individual enumerators and 
tweak the documentation for deprecation-with-message.  Provide __has_feature
tests for both.  rdar://problem/8605692

5ef9e33137 Make the deserialization of macro definitions lazy, so that we can 
load identifiers without loading their corresponding macro
definitions. This is likely to improve PCH performance slightly, and
reduces deserialization stack depth considerably when using
preprocessor metaprogramming.

796d76a663 Extend the preprocessing record and libclang with support for 
inclusion directives, keeping track of every #include, #import,
etc. in the translation unit. We keep track of the source location and
kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

fde85356c6 revert my patch for rdar://7520940 that warns when a published header 
is #included with "foo.h" style syntax instead of framework syntax.

af4e28d897 Add a bunch more feature-checking macros for C++0x features. Some of these are 
disabled with the intent that users can start with them now and not have to change
a thing to have them work when we implement the features.

b6f77af532 implement and document a new __has_feature and __has_builtin magic 
builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).

f160b5f9e1 When we expect two arguments but have zero, make sure to add 
two empty arguments.  Also, add an assert so that this bug
manifests as an assertion failure, not a valgrind problem.

c17925da61 Substantially restructure function-like macro argument parsing. 
Highlights: PP::isNextPPTokenLParen() no longer eats the (

macro arguments.  We now handle PR3937 and other related cases
correctly.
