This is the `ext_vector_type` alternative to D81083.
This patch extends Clang to allow 'bool' as a valid vector element type
(attribute ext_vector_type) in C/C++.
This is intended as the canonical type for SIMD masks and facilitates
clean vector intrinsic declarations. Vectors of i1 are supported on IR
level and below down to many SIMD ISAs, such as AVX512, ARM SVE (fixed
vector length) and the VE target (NEC SX-Aurora TSUBASA).

`.rgba` vector extension setting in C++ for OpenCL 2021 is now
performed analogously to OpenCL C 3.0. Test case added.

Some Clang diagnostics could only report OpenCL C version. Because
C++ for OpenCL can be used as an alternative to OpenCL C, the text
for diagnostics should reflect that.
Desrciptions modified for these diagnostics:
`err_opencl_unknown_type_specifier`
`warn_option_invalid_ocl_version`
`err_attribute_requires_opencl_version`
`warn_opencl_attr_deprecated_ignored`
`ext_opencl_ext_vector_type_rgba_selector`

The .rgba vector component accessors are supported in OpenCL C 3.0.
Previously, the diagnostic would check `OpenCLVersion` for version 2.2
(value 220) and report those accessors are an OpenCL 2.2 feature.
However, there is no "OpenCL C version 2.2", so change the check and
diagnostic text to 3.0 only.
A spurious `OpenCLVersion` argument was passed into the diagnostic;
remove that.

Summary:
This patch enables .rgba accessors to ext_vector_type types and adds
tests for syntax validation and code generation.
'a' and 'b' can appear either in the point access mode or the numeric
access mode (for indices 10 and 11). To disambiguate between the two
usages, the accessor type is explicitly passed to relevant methods.
