  [clang-check] Adjust argument adjusters for clang-check to strip options blocking the static analyzer

Output generation options (like `-save-temps`) will make the analyzer not executed even `--analyze` option is provided in the driver arguments.
Besides, the original approach of adding `--analyze` option will not work when (more than one) `-fsyntax-only` options are provided in the driver arguments.

This patch fixes these two problems by using the syntax-only adjuster to remove output generation options and manually filter out redundant `-fsyntax-only` options.

In the new implementation, the adjusters added by `ClangTool` will not be removed but used as dependencies for clang-check adjusters for analyzer options.
