[clang] accept -fsanitize-ignorelist= in addition to -fsanitize-blacklist= Use that for internal names (including the default ignorelists of the sanitizers). Differential Revision: https://reviews.llvm.org/D101832

Add the -fsanitize=shadow-call-stack flag Summary: Add support for the -fsanitize=shadow-call-stack flag which causes clang to add ShadowCallStack attribute to functions compiled with that flag enabled.

[RISCV] Support Shadow Call Stack Currenlty assume x18 is used as pointer to shadow call stack. User shall pass flags: "-fsanitize=shadow-call-stack -ffixed-x18" Runtime supported is needed to setup x18. If SCS is desired, all parts of the program should be built with -ffixed-x18 to maintain inter-operatability. There's no particuluar reason that we must use x18 as SCS pointer. Any register may be used, as long as it does not have designated purpose already, like RA or passing call arguments. Differential Revision: https://reviews.llvm.org/D84414
