    analyzer: fix ICE on __builtin_ms_va_copy [PR105765]

    gcc/analyzer/ChangeLog:
            PR analyzer/105765
            * varargs.cc (get_BT_VALIST_ARG): Rename to...
            (get_va_copy_arg): ...this, and update logic for determining le=
vel
            of indirection of va_copy's argument to use type of argument,
            rather than looking at va_list_type_node, to correctly handle
            __builtin_ms_va_copy.
            (get_stateful_BT_VALIST_ARG): Rename to...
            (get_stateful_va_copy_arg): ...this.
            (va_list_state_machine::on_va_copy): Update for renaming.
            (region_model::impl_call_va_copy): Likewise.

    gcc/testsuite/ChangeLog:
            PR analyzer/105765
            * gcc.dg/analyzer/stdarg-1-ms_abi.c: New test, based on stdarg-=
1.c.
            * gcc.dg/analyzer/stdarg-1-sysv_abi.c: Likewise.
