Add the sub-group builtin functions from the OpenCL Extension
specification. This patch excludes the sub_group_barrier builtins
that take argument types not yet handled by the
`-fdeclare-opencl-builtins` machinery.

The `-fdeclare-opencl-builtins` option was accepting saturated
conversions for non-integer types, which contradicts both the OpenCL
specification (v2.0 s6.2.3) and Clang's opencl-c.h file.
Provide a mechanism to attach OpenCL extension information to builtin
functions, so that their use can be restricted according to the
extension(s) the builtin is part of.

Support for C++ mode was accidentally lacking due to not checking the
OpenCLCPlusPlus LangOpts version.

Add the -Wconversion -Werror options to check no unexpected conversion
is done.

Allow setting a MinVersion, stating from which OpenCL version a
builtin function is available, and a MaxVersion, stating from which
OpenCL version a builtin function should not be available anymore.
Guard some definitions of the "work-item" builtin functions according
to the OpenCL versions from which they are available.
Add the "vector data load and store" builtin functions (e.g.
vload/vstore), whose signatures differ before and after OpenCL 2.0 in
the pointer argument address spaces.

Image types were previously available, but not working. This patch
adds image type handling.
Rename the image type definitions in the .td file to make them
consistent with other type names. Use abstract types to represent the
unqualified types. Instantiate access-qualified image types at the
point of use using, e.g. `ImageType<Image2d, "RO">`.
Add/update TableGen definitions for the read_image/write_image
builtin functions.

Const, volatile, and pointer types were previously available, but not
working. This patch adds handling for OpenCL builtin functions.
Add TableGen definitions for some atomic and asynchronous builtins to
make use of the new functionality.

Generic types are an abstraction of type sets. It mimics the way
functions are defined in the OpenCL specification. For example,
floatN can abstract all the vector sizes of the float type.
This allows to
* stick more closely to the specification, which uses generic types;
* factorize definitions of functions with numerous prototypes in the
tablegen file; and
* reduce the memory impact of functions with many overloads.

Using the -fdeclare-opencl-builtins option will require a way to
predefine types and macros such as `int4`, `CLK_GLOBAL_MEM_FENCE`,
etc. Move these out of opencl-c.h into opencl-c-base.h such that the
latter can be shared by -fdeclare-opencl-builtins and
-finclude-default-header.
This changes the behaviour of -finclude-default-header when
-fdeclare-opencl-builtins is specified: instead of including the full
header, it will include the header with only the base definitions.

This patch adds a `-fdeclare-opencl-builtins` command line option to
the clang frontend. This enables clang to verify OpenCL C builtin
function declarations using a fast StringMatcher lookup, instead of
including the opencl-c.h file with the `-finclude-default-header`
option. This avoids the large parse time penalty of the header file.
This commit only adds the basic infrastructure and some of the OpenCL
builtins. It does not cover all builtins defined by the various OpenCL
specifications. As such, it is not a replacement for
`-finclude-default-header` yet.
