Within the body of the loop the underlying map may be modified via

  Sema::AddOverloadCandidate
    -> Sema::CompareReferenceRelationship
    -> Sema::RequireCompleteType

to avoid the use of invalid iterators the sequence is copied first.

A reliable, though large, test case is available - it will be reduced and
committed shortly.

block, which stores information about how the AST file to generated,
from the AST block, which stores the actual serialized AST. The
information in the control block should be enough to determine whether
the AST file is up-to-date and compatible with the current translation
unit, and reading it should not cause any side effects that aren't
easy to undo. That way, we can back out from an attempt to read an
incompatible or out-of-date AST file.

Note that there is still more factoring to do. In particular,
information about the source files used to generate the AST file
(along with their time stamps, sizes, etc.) still resides in the
source manager block.

Fix -Woverloaded-virtual when the using statement refers to a base declaration of a virtual function.

GCC and Clang both do not warn on:

  struct a { virtual void func(); };
  struct b: a { virtual void func(); void func(int); };
  struct c: b { void func(int); using b::func; };

but if the "using" was using a::func GCC would still remain silent where Clang
would warn. This change makes Clang consistent with GCC's existing behavior.

This actually looks through several kinds of expression, such as
OpaqueValueExpr and ExprWithCleanups. The idea is that binding and lookup
should be consistent, and so if the environment needs to be modified later,
the code doing the modification will not have to manually look through these
"transparent" expressions to find the real binding to change.

This is necessary for proper updating of struct rvalues as described in
the previous commit.

llvm-svn: 166121

In C++, rvalues that need to have their address taken (for example, to be
passed to a function by const reference) will be wrapped in a
MaterializeTemporaryExpr, which lets CodeGen know to create a temporary
region to store this value. However, MaterializeTemporaryExprs are /not/
created when a method is called on an rvalue struct, even though the 'this'
pointer needs a valid value. CodeGen works around this by creating a
temporary region anyway; now, so does the analyzer.

The analyzer also does this when accessing a field of a struct rvalue.
This is a little unfortunate, since the rest of the struct will soon be
thrown away, but it does make things consistent with the rest of the
analyzer.

This allows us to bring back the assumption that all known 'this' values
are Locs. This is a revised version of r164828-9, reverted in r164876-7.

combination of a load+objc_release;  this is generally better
for tools that try to track why values are retained and
released.  Also use objc_storeStrong when copying a block
(again, only at -O0), which requires us to do a preliminary
store of null in order to compensate for objc_storeStrong's
assign semantics.
