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.
