Removing has_getDecl (added in r175532). It cause a build break for MSVC, and was not yet being used in the codebase. If we start using std::enable_if, we can look into resurrecting the idea in a more portable fashion.

Added a footnote to the documentation for objc_storeStrong that makes it clear
that a __strong object of block type is a valid argument to objc_storeStrong but
that an objc_retain and not an objc_retainBlock will be emitted.

Preproceessor: fix #if skipping under -traditional-cpp.

When parsing directives within skipped #if blocks, we don't want to retain
any whitespace. Previously we were just skipping comments, but it's not
possible to skip comments and retain other whitespace. This change matches
the usual behavior for parsing directives (i.e. the behavior outside of
skipped #if blocks).

[analyzer] Make sure a materialized temporary matches its bindings.

This is a follow-up to r175830, which made sure a temporary object region
created for, say, a struct rvalue matched up with the initial bindings
being stored into it. This does the same for the case in which the AST
actually tells us that we need to create a temporary via a
MaterializeObjectExpr. I've unified the two code paths and moved a static
helper function onto ExprEngine.

This also caused a bit of test churn, causing us to go back to describing
temporary regions without a 'const' qualifier. This seems acceptable; it's
our behavior from a few months ago.

Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,
to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting
levels for parentheses, brackets and braces.

Some code with heavy macro use exceeds the default limit of 256, but we don't
want to increase it generally to avoid stack overflow on stack-constrained
systems.

[analyzer] Place all inlining policy checks into one palce

Previously, we had the decisions about inlining spread out
over multiple functions.

In addition to the refactor, this commit ensures
that we will always inline BodyFarm functions as long as the Decl
is available. This fixes false positives due to those functions
not being inlined when no or minimal inlining is enabled such (as
shallow mode).

Only suppress instance context if a member is actually
accessible in its declaring class;  otherwise we might
fail to apply [class.protected] when considering
accessibility in derived classes.

Noticed by inspection; <rdar://13270329>.

I had an existing test wrong.  Here's why it's wrong:

Follow the rules (and notation) of [class.access]p5.
The naming class (N) is B and the context (R) is D::getX.
- 'x' as a member of B is protected, but R does not occur
  in a member or friend of a class derived from B.
- There does exist a base class of B, A, which is accessible
  from R, and 'x' is accessible at R when named in A because
  'x' as a member of A is protected and R occurs in a member
  of a class, D, that is derived from A;  however, by
  [class.protected], the class of the object expression must
  be equal to or derived from that class, and A does not
  derive from D.

Implement C++11 [dcl.align]p6-p8, and C11 6.7.5/7. This had to be split out of
the normal attribute-merging path, because we can't merge alignment attributes

particular declaration.
