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).
