This patch adds type conversion for 4 SPIR-V types: array, runtime array, pointer and struct. This conversion is integrated using a separate function `populateSPIRVToLLVMTypeConversion()` that adds new type conversions. At the moment, this is a basic skeleton that allows to perfom conversion from SPIR-V array, runtime array and pointer types to LLVM typesystem. There is no support of array strides or storage classes. These will be supported on the case by case basis. Reviewed By: antiagainst Differential Revision: https://reviews.llvm.org/D83399
