Until now, subgroup builtins are available with `opencl-c.h` when at
least one of `cl_intel_subgroups`, `cl_khr_subgroups`, or
`__opencl_c_subgroups` is defined. With `-fdeclare-opencl-builtins`,
subgroup builtins are conditionalized on `cl_khr_subgroups` only.
Align `-fdeclare-opencl-builtins` to `opencl-c.h` by introducing the
internal `__opencl_subgroup_builtins` macro.

Commit 3c7d2f1b67 ("[OpenCL] opencl-c.h: add CL 3.0 non-generic
address space atomics", 2021-07-30) added some atomic_fetch_add/sub
overloads with uintptr_t arguments twice. Instead, they should have
been atomic_fetch_max overloads with non-generic address spaces.
The named address space overloads of builtins that take a pointer
argument are conditionalized on the `__opencl_c_generic_address_space`
feature macro (in a `#else` body). Introduce an internal feature
macro instead, such that their availability can be controlled in a
single place and independently of the generic address space feature
macro.
This commit does not change the available builtins.
Differential Revision: https://reviews.llvm.org/D118158
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.

Add new triple and target info for ‘spirv32’ and ‘spirv64’ and,
thus, enabling clang (LLVM IR) code emission to SPIR-V target.
The target for SPIR-V is mostly reused from SPIR by derivation
from a common base class since IR output for SPIR-V is mostly
the same as SPIR. Some refactoring are made accordingly.
Added and updated tests for parts that are different between
SPIR and SPIR-V.

Atomics in C++ for OpenCL 2021 are now handled the same way as in
OpenCL C 3.0. This is a header-only change.
Differential Revision: https://reviews.llvm.org/D109424
CL 2.0 introduced atomics and generic address space so there were
only one set of APIs for doing atomics, however since CL 3.0
makes generic address space optional, there has to be new sets
of atomic interfaces to handle that cases.

This adds the optional wrappers around things, however this isn't sufficient yet for CL 3.0 without generic address space, I've got one more additional patch to add all those APIs, but this is an easier to review precursor.

This just reorders the atomics, it doesn't change anything except their layout in the header.
This is a prep patch for adding some conditionals around these for CL3.0 but that patch is much easier to review if all the atomic operations are grouped together like this.

This removed the pointless need for extension pragma since
it doesn't disable anything properly and it doesn't need to
enable anything that is not possible to disable.
The change doesn't break existing kernels since it allows to
compile more cases i.e. without pragma statements but the
pragma continues to be accepted.

Move any remaining preprocessor defines from `opencl-c.h` to
`opencl-c-base.h`, such that they are shared with
`-fdeclare-opencl-builtins` too.

Supporting `printf` with `-fdeclare-opencl-builtins` would require

opencl-c.h disables all extensions at its end, but opencl-c-base.h
does not, and that causes any inclusion of only opencl-c-base.h to
leave some extensions (such as cl_khr_fp16) enabled. This affects the
-fdeclare-opencl-builtins option for example.
This violates the OpenCL Extension Specification which specifies that
"The initial state of the compiler is as if the directive #pragma
OPENCL EXTENSION all : disable was issued".
Fix by disabling all extensions at the end of opencl-c-base.h and
enable extensions inside opencl.h which relied on opencl-c-base.h
enabling the cl_khr_fp16/64 extensions.
