The driver uses class SanitizerArgs to store parsed sanitizer arguments. It keeps a cached SanitizerArgs object in ToolChain and uses it for different jobs. This does not work if the sanitizer options are different for different jobs, which could happen when an offloading toolchain translates the options for different jobs. To fix this, SanitizerArgs should be created by using the actual arguments passed to jobs instead of the original arguments passed to the driver, since the toolchain may change the original arguments. And the sanitizer arguments should be diagnose once. This patch also fixes HIP toolchain for handling -fgpu-sanitize: a warning is emitted for GPU's not supporting sanitizer and skipped. This is for backward compatibility with existing -fsanitize options. -fgpu-sanitize is also turned on by default.
