Francois Pichet 0706d203cf Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag.
Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag.

John McCall b46f287e48 Clean up the sentinel-attribute checking code a lot. Document
what 'nullPos' is supposed to mean, at least at this one site.
Use closed forms for the arithmetic.  Rip out some clever but
ultimately pointless code that was trying to use 0 or 0L depending
the size of a pointer vs. the size of int;  first, it didn't work
on LLP64 systems, and second, the sentinel checking code requires
a pointer-typed value anyway, so this fixit would not have actually
removed the warning.

Douglas Gregor e8bbc12152 Extend the ASTContext constructor to delay the initialization of
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

Caitlin Sadowski afbbd8e5ad Thread-safety analysis: adding in a basic lockset tracking system. This
system flags an error when unlocking a lock which was not held, locking
the same lock twice, having a different lockset on each iteration of a
loop, or going out of scope while still holding a lock. In order to
successfully use the lockset, this patch also makes sure that attribute
arguments are attached correctly for later parsing.

This patch was also worked on by DeLesley Hutchins.

Note: This patch has been reviewed by Chandler Carruth and Jeffrey
Yasskin. Feel free to provide post-commit review comments for a
subsequent patch.

Caitlin Sadowski 4b1e8399c2 Thread Safety: Added basic argument parsing for all new attributes.
This patch special cases the parser for thread safety attributes so that all
attribute arguments are put in the argument list (instead of a special
parameter) since arguments may not otherwise resolve correctly without two-token
lookahead.

This patch also adds checks to make sure that attribute arguments are
lockable objects.

Chandler Carruth ff4c4f0f8a Mechanical rename of 'd' Decl pointer parameters to 'D'. This is more
conventional in the rest of Clang's codebase, and closer to the current
style recommendations. It also makes the code more internally consistent
as FD, VD, etc are used frequently for particular decl variables.

Chandler Carruth c91f09d73a Fix an obvious typo in an attribute's diagnostics.
Patch by Caitlin Sadowski.

Unfortunately, this attribute doesn't seem to have a single test. It is
only mentioned in comments in one test, and as a string literal in
a copy of some Clang code checked in as a test for the Indexer. =[ It
dates from 2009 r74280 as part of OpenCL 1.0.

Douglas Gregor 39c0272f65 Eliminate a 'default' case in template argument deduction, where we
were just punting on template argument deduction for a number of type
nodes. Most of them, obviously, didn't matter.

As a consequence of this, make extended vector types (via the
ext_vector_type attribute) actually work properly for several
important cases:
  - If the attribute appears in a type-id (i.e, not attached to a
  typedef), actually build a proper vector type
  - Build ExtVectorType whenever the size is constant; previously, we
  were building DependentSizedExtVectorType when the size was constant
  but the type was dependent, which makes no sense at all.
  - Teach template argument deduction to handle
  ExtVectorType/DependentSizedExtVectorType.

Anton Korobeynikov 231e875b5c Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or
