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.

Some opcodes in generic MIR represent calls to intrinsics, where the intrinsic
ID is the first non-def operand to the instruction. These are now represented as
a subclass of GenericMachineInstr, and the method MachineInstr::getIntrinsicID()
is now moved to this subclass GIntrinsic.
Some target-defined instructions behave like GMIR intrinsics, and have an
Intrinsic::ID operand. But they should not be recognized as generic intrinsics,
and should not use GIntrinsic::getIntrinsicID(). Separated these out by
introducing a new AMDGPU::getIntrinsicID().

After this patch all arbitrary size integers (smaller than 64 bits) in
LLVM IR will be promoted to regular size type in SPIR-V (OpTypeInt
8/16/32/64).

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.

SPIRVModuleAnalysis collects module and external function registers
(usually result of OpFunction) for use when emitting OpFunctionCall.
This patch makes the mapping between the functions and registers using
pointers (instead of name strings) to ensure anonymous functions and
calls can be resolved properly.

It is implemented in the same way as in the SPIRV translator.

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.

The patch replaces SPIRVBaseInfo.* previously created using macros by
the tablegen approach. There are many small changes in other files due to
differences in namespaces. Also, functions in SPIRVUtils are moved to
the llvm namespace.

The patch adds SPIRVPrepareFunctions pass, which modifies function
signatures containing aggregate arguments and/or return values before
IR translation. Information about the original signatures is stored in
metadata. It is used during call lowering to restore correct SPIR-V types
of function arguments and return values. This pass also substitutes some
llvm intrinsic calls to function calls, generating the necessary functions
in the module, as the SPIRV translator does.
The patch also includes changes in other modules, fixing errors and
enabling many SPIR-V features that were omitted earlier. And 15 LIT tests
are also added to demonstrate the new functionality.

The patch adds SPIR-V specific intrinsics required to keep information
critical to SPIR-V consistency (types, constants, etc.) during translation
from IR to MIR.
Two related passes (SPIRVEmitIntrinsics and SPIRVPreLegalizer) and several
LIT tests (passed with this change) have also been added.
It also fixes the issue with opaque pointers in SPIRVGlobalRegistry.cpp
and the mismatch of the data layout between the SPIR-V backend and clang
(Issue #55122).
