Add spirv-dis (disassembler) and spirv-val (validator) from SPIRV-Tools as external dependencies for testing the SPIR-V backend. These tools are test dependencies only. SPIR-V backend tests now have a dependency on the spirv-dis and spirv-val targets when the `LLVM_INCLUDE_SPIRV_TOOLS_TESTS` cmake variable is set, which allows additional test files with the `REQUIRES: spirv-tools` constraint to run, along with additional `RUN: %if spirv-tools ...` lines in existing tests. All other SPIR-V backend tests will run normally when `LLVM_INCLUDE_SPIRV_TOOLS_TESTS` is not set. Several tests are included to show these tools' use, however more tests will be migrated and added later. * OpVariable_order.ll shows how spirv-val can catch bugs in the backend. * basic_int_types_spirvdis.ll shows how tests can be much shorter and more readable by FileChecking the spirv-dis output. * basic_int_types.ll shows how an additional RUN line can add validation to existing tests.
