Replace r155185 with a better fix, which also addresses PR12557. When looking
up an elaborated type specifier in a friend declaration, only look for type
declarations, per [basic.lookup.elab]p2. If we know that the redeclaration
lookup for a friend class template in a dependent context finds a non-template,
don't delay the diagnostic to instantiation time.

Fix bug where a class's (deleted) copy constructor would be implicitly given a
non-const reference parameter type if the class had any subobjects with deleted
copy constructors. This causes a rejects-valid if the class's copy constructor
is explicitly defaulted (as happens for some implementations of std::pair etc).

In r135308, -save-temps was modified to prevent a temporary file from
overwriting the input file.  For example,

clang -c foo.s -o foo.o -save-temps

Unfortunately, the original patch didn't compare the paths of the input and
output files.  Thus, something like the following would fail to create foo.s.

cd /tmp/obj
clang -c ../src/foo.s -o foo.o -save-temps

[analyzer] Run remove dead bindings right before leaving a function.

This is needed to ensure that we always report issues in the correct
function. For example, leaks are identified when we call remove dead
bindings. In order to make sure we report a callee's leak in the callee,
we have to run the operation in the callee's context.

This change required quite a bit of infrastructure work since:
 - We used to only run remove dead bindings before a given statement;
here we need to run it after the last statement in the function. For
this, we added additional Program Point and special mode in the
SymbolReaper to remove all symbols in context lower than the current
one.
 - The call exit operation turned into a sequence of nodes, which are
now guarded by CallExitBegin and CallExitEnd nodes for clarity and
convenience.

(Sorry for the long diff.)

[libclang] Don't set dylib load address to 0xe000000.

Per Greg Clayton:
libclang.dylib is trying to be smart and load itself at a valid address
to be able to load faster which would work for 32 bit systems,
bit won't make any difference on 64 bit systems.
It should either pick a better 64 bit address, or just let itself be loaded at zero.

Fix a QoI bug reported by a user.

Set the source location for the "member reference base type ... is not a
structure or union" diag to point at the operator rather than the member name.
If we're giving this diagnostic because of a typo'd '.' in place of a ';' at
the end of a line, the caret previously pointed at the identifier on the
following line, which isn't as helpful as it could be. Pointing the caret at
the '.' makes it more obvious what the problem is.
