Chih-Hung Hsieh 83494d2f8c [Tooling] Allow -flto flags and filter out -Wa, flags
This change fixes the problem in https://bugs.llvm.org/show_bug.cgi?id=38332
by allowing driver::Action::BackendJobClass to run with the analyzer.
Otherwise, such jobs will look up the non-existing compilation database
and then run without flags.
Also filter out the -Wa,* flags that could be passed to and ignored
by the clang compiler.  Clang-tidy gives warnings about unused -Wa,* flags.
