Add printing of __private address space to TypePrinter to allow
it appears in diagnostics and AST dumps as all other language
addr spaces.

In order to simplify implementation we are moving add space
deduction into Sema while constructing variable declaration
and on template instantiation. Pointee are deduced to generic
addr space during creation of types.
This commit also
- fixed addr space dedution for auto type;
- factors out in a separate helper function OpenCL specific
logic from type diagnostics in var decl.

Block captures can have different physical locations
in memory segments depending on the use case (as a function
call or as a kernel enqueue) and in different vendor
implementations.
Therefore it's unclear how to add address space to capture
addresses uniformly. Currently it has been decided to disallow
taking addresses of captured variables until further
clarifications in the spec.

Modify ObjC blocks impl wrt address spaces as follows:
- keep default private address space for blocks generated
as local variables (with captures);
- add global address space for global block literals (no captures);
- make the block invoke function and enqueue_kernel prototype with
the generic AS block pointer parameter to accommodate both
private and global AS cases from above;
- add block handling into default AS because it's implemented as
a special pointer type (BlockPointer) in the frontend and therefore
it is used as a pointer everywhere. This is also needed to accommodate
both private and global AS blocks for the two cases above.
- removes ObjC RT specific symbols (NSConcreteStackBlock and
NSConcreteGlobalBlock) in the OpenCL mode.

OpenCL disallows using variadic arguments (s6.9.e and s6.12.5 OpenCL v2.0)
apart from some exceptions:
- printf
- enqueue_kernel
This change adds error diagnostic for variadic functions but accepts printf
and any compiler internal function (which should cover __enqueue_kernel_XXX cases).
It also unifies diagnostic with block prototype and adds missing uncaught cases for blocks.

- Changes diagnostics for Blocks to be implicitly
const qualified OpenCL v2.0 s6.12.5.
- Added and unified diagnostics of some OpenCL special types:
blocks, images, samplers, pipes. These types are intended for use
with the OpenCL builtin functions only and, therefore, most regular
uses are not allowed including assignments, arithmetic operations,
pointer dereferencing, etc.

Applying the following restrictions for block types in OpenCL (v2.0 s6.12.5):
- __block storage class is disallowed
- every block declaration must be const qualified and initialized
- a block can't be used as a return type of a function
- a blocks can't be used to declare a structure or union field
- extern speficier is disallowed
Corrected image and sampler types diagnostics with struct and unions.
