Add --cmake-toolchain and --remote-host flags for test-suite (#35)

When cross-compiling LLVM test-suite to run on another machine, you usually need to pass a toolchain file and -DTEST_SUITE_REMOTE_HOST to CMake.

This adds two flags to the CLI to make it more convenient to configure these (as opposed to passing in -DCMAKE_TOOLCHAIN_FILE/-DTEST_SUITE_REMOTE_HOST)
