When we create overloads for the builtin compound assignment operators
we need to preserve address space for the reference operand taking it
from the argument that is passed in.

This change adds a new diagnostic for mismatching address spaces
to be used for C++ casts (only enabled in C style cast for now,
the rest will follow!).
The change extends C-style cast rules to account for address spaces.
It also adds a separate function for address space cast checking that
can be used to map from a separate address space cast operator
addrspace_cast (to be added as a follow up patch).
Note, that after this change clang will no longer allows arbitrary
address space conversions in reinterpret_casts because they can lead
to accidental errors. The implicit safe conversions would still be
allowed.

Adjust address space for references and pointer operands of builtin operators.
Currently this change only fixes addr space in assignment (= and |=) operator,
that is needed for the test case reported in the bug. Wider support for all
other operations will follow.

The address space for the Base class pointer when up-casting
from Derived should be taken from the Derived class pointer.

This change fixes temporary materialization to happen in the right
(default) address space when binding to it a reference of different type.
It adds address space conversion afterwards to match the addr space
of a reference.

When creating the prototype of implicit assignment operators the
returned reference to the class should be qualified with the same
addr space as 'this' (i.e. __generic in OpenCL).

Methods can now be qualified with address spaces to prevent
undesirable conversions to generic or to provide custom
implementation to be used if the object is located in certain
memory segments.
This commit extends parsing and standard C++ overloading to
work for an address space of a method (i.e. implicit 'this'
parameter).

Set address spaces of 'this' param correctly for implicit special
class members.
This also changes initialization conversion sequence to separate
address space conversion from other qualifiers in case of binding
reference to a temporary. In this case address space conversion
should happen after the binding (unlike for other quals). This is
needed to materialize it correctly in the alloca address space.

Address spaces are cast into generic before invoking the constructor.
Added support for a trailing Qualifiers object in FunctionProtoType.
Note: This recommits the previously reverted patch,
but now it is commited together with a fix for lldb.

Fix ICEs on template instantiations that were leading to
the creation of invalid code patterns with address spaces.
Incorrect cases are now diagnosed properly.

Added references to the addr spaces deduction and enabled
CL2.0 features (program scope variables and storage class
qualifiers) to work in C++ mode too.
Fixed several address space conversion issues in CodeGen
for references.
