[SYCL] Re-land "Represent JointMatrixINTEL type as extension type" (#9841)

MrSidims · bader · web-flow · commit c063b99843d6 · 2023-06-14T08:00:40.000-07:00
This reverts commit 4447a50. Previous attempt: #8343 What changed: One extra patch is being added to the headers: ca0595b with this patch clang won't generate llvm.memcpy for trivial c'tor. So later on inst combine won't replace it with a cast to i64 followed by load + store which SROA + mem2reg won't be able to handle for target extension types. It adds: ConvertSYCLJointMatrixINTELType - Convert SYCL joint_matrix type which is represented as a pointer to a structure to LLVM extension type with the parameters that follow SPIR-V JointMatrixINTEL type. The expected representation is: target("spirv.JointMatrixINTEL", %element_type, %rows%, %cols%, %scope%, %use%, (optional) %element_type_interpretation%) Better approach is to introduce joint matrix type to clang, but it's off the table now, since we are lacking OpenCL spec.
