This PR: * fixes OpVariable instructions place in a function (see https://github.com/llvm/llvm-project/issues/66261), * improves type inference, * helps avoiding unneeded bitcasts when validating function call's This allows to improve existing and add new test cases with more strict checks. OpVariable fix refers to "All OpVariable instructions in a function must be the first instructions in the first block" requirement from SPIR-V spec.
