Aaron Ballman 22db4824b9 Use functions with prototypes when appropriate; NFC
A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the third batch of tests being updated (there are a significant
number of other tests left to be updated).

Anton Zabaznov a5de66c4c5 [OpenCL] Add support of __opencl_c_device_enqueue feature macro.
This feature requires support of __opencl_c_generic_address_space and
__opencl_c_program_scope_global_variables so diagnostics for that is provided as well.

Sven van Haastregt bd46a56474 [OpenCL] Reject block arguments
OpenCL 2.0 does not allow block arguments, primarily because it is
difficult to support function pointers on the various architectures
that OpenCL targets.  Clang was still accepting them.

Rename and reuse the `err_opencl_half_param` diagnostic.

Fixes PR46324.

Anastasia Stulova 869d17d851 [OpenCL] Pretty print __private addr space
Add printing of __private address space to TypePrinter to allow
it appears in diagnostics and AST dumps as all other language
addr spaces.

Anastasia Stulova a29aa47106 [OpenCL] Move addr space deduction to Sema.
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.

Anastasia Stulova 257132a019 [OpenCL] Handle taking an address of block captures.
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.

Anastasia Stulova af0a7bbbe2 [OpenCL] Add missing address spaces in IR generation of blocks
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.

Anastasia Stulova 7c30533362 [OpenCL] Diagnose variadic arguments
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.

Anastasia Stulova 4d85003964 [OpenCL] Improved diagnostics of OpenCL types.
- 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.

Anastasia Stulova 1f95cc097c [OpenCL] Apply missing restrictions for Blocks in OpenCL v2.0
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.
