This PR: * adds support for G_SPLAT_VECTOR generic opcode that may be legally generated instead of G_BUILD_VECTOR by previous passes of the translator (see https://github.com/llvm/llvm-project/pull/80378 for the source of breaking changes); * improves deduction of types for opaque pointers. This PR also fixes the following issues: * if a function has ptr argument(s), two functions that have different SPIR-V type definitions may get identical LLVM function types and break agreements of global register and duplicate checker; * checks for pointer types do not account for TypedPointerType. Update of tests: * A test case is added to cover the issue with function ptr parameters. * The first case, that is support for G_SPLAT_VECTOR generic opcode, is covered by existing test cases. * Multiple additional checks by `spirv-val` is added to cover more possibilities of generation of invalid code.
