    runtime: use libc for signal functions on iOS · 021c39d7

    Also:
     - Add extra SystemStack space for darwin/arm64 just
    like for darwin/arm.
     - Removed redundant stack alignment; the arm64 hardware enforces
     the 16 byte alignment.
     - Save and restore the g registers at library initialization.
     - Zero g registers since libpreinit can call libc functions
     that in turn use asmcgocall. asmcgocall requires an initialized g.
     - Change asmcgocall to work even if no g is set. The change mimics
     amd64.
