Introduced the convergent equivalent of the existing G_INTRINSIC opcodes:
- G_INTRINSIC_CONVERGENT
- G_INTRINSIC_CONVERGENT_W_SIDE_EFFECTS
Out of the targets that currently have some support for GlobalISel, the patch
assumes that the convergent intrinsics only relevant to SPIRV and AMDGPU.

The patch fixes "Virtual register does not match instruction constraint"
and partly "Illegal virtual register for instruction" fails in the SPIRV
backend builds with LLVM_ENABLE_EXPENSIVE_CHECKS enabled. As a result,
the number of passed LIT tests with enabled checks is doubled.
Also, support for ndrange_*D builtins is placed in a separate function.

This patch adds support for TargetExtType/target(...) representing
SPIR-V builtin types. After D135202, target(...) is the preferred way
for representing SPIR-V builtin types in LLVM IR and the only working
in the opaque pointer mode.
In order to maintain compatibility with LLVM IR generated by older
versions of Clang and LLVM/SPIR-V Translator, pointers-to-opaque-structs
denoting SPIR-V/OpenCL builtin types will be translated to equivalent
SPIR-V target extension types. This translation is only available in the
typed pointer mode (-opaque-pointers=0).
The relevant LIT tests with SPIR-V builtins were converted to use the
new target(...) notation.

This change provides implementation details for atomic_flag builtins and
adds an extended atomic_flag.ll test from the LLVM SPIR-V Translator.

The patch adds support of the enqueue_kernel builtin function.
It is implemented in the same way as in the SPIRV translator.

UndefValue with PoisonValue in SPIRVRegularizer.cpp.
Fixes: #57773
Differential Revision: https://reviews.llvm.org/D134071
The patch adds the regularization pass that prepare LLVM IR for
the IR translation. It also contains following changes:
- reduce indentation, make getNonParametrizedType, getSamplerType,
getPipeType, getImageType, getSampledImageType static in SPIRVBuiltins,
- rename mayBeOclOrSpirvBuiltin to getOclOrSpirvBuiltinDemangledName,
- move isOpenCLBuiltinType, isSPIRVBuiltinType, isSpecialType from
SPIRVGlobalRegistry.cpp to SPIRVUtils.cpp, renaming isSpecialType to
isSpecialOpaqueType,
- implment getTgtMemIntrinsic() in SPIRVISelLowering,
- add hasSideEffects = 0 in Pseudo (SPIRVInstrFormats.td),
- add legalization rule for G_MEMSET, correct G_BRCOND rule,
- add capability processing for OpBuildNDRange in SPIRVModuleAnalysis,
- don't correct types of registers holding constants and used in
G_ADDRSPACE_CAST (SPIRVPreLegalizer.cpp),
- lower memset/bswap intrinsics to functions in SPIRVPrepareFunctions,
- change TargetLoweringObjectFileELF to SPIRVTargetObjectFile
in SPIRVTargetMachine.cpp,
- correct comments.
5 LIT tests are added to show the improvement.

The patch adds the support of OpenCL and SPIR-V built-in types. It also
implements ExtInst selection and adds spv_unreachable and spv_alloca
intrinsics which improve the generation of the corresponding SPIR-V code.
Five LIT tests are included to demonstrate the improvement.
