This PR resolves the issue that SPIR-V Backend uses the notion of a pointer size of the target, most notably, in legalizer code, but Tablegen instruction selection in SPIR-V Backend doesn't account for a pointer size of the target. See https://github.com/llvm/llvm-project/issues/88723 for a detailed description. There are 3 test cases attached to the PR that reproduced the issue, when dealing with spirv32-spirv64 differences, and are working correctly now with this PR.
