This patch disables MachineLateInstrsCleanup pass (since it does not
work with virtual registers) and modifies LIT tests to run with -O0.
Differential Revision: https://reviews.llvm.org/D140103
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 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).

This patch adds one SPIRV analysis pass and extends AsmPrinter. It is
essential for minimum SPIR-V output. Also it adds several simplest tests
to show that the target basically works.
