Clang's builtin for clear_cache accepts char* and errors out when using void*,
using char* work on both gcc and clang since char* is auto-converted to void* in gcc case

Source/JavaScriptCore/assembler/ARM64Assembler.h:2857:33: error: cannot initialize a parameter of type 'char *' with an rvalue of type 'void *'
        __builtin___clear_cache(reinterpret_cast<void*>(begin), reinterpret_cast<void*>(end));
                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
