Make Emacs buildable with -std=c11.

With -std=c11, GCC doesn't recognize 'asm' as a keyword, see
https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html and
https://gcc.gnu.org/onlinedocs/gcc/Alternate-Keywords.html.  Use __asm__
instead.

* src/lisp.h (flush_stack_call_func): Use __asm__ instead of asm.

(cherry picked from commit e978737f57ef8447bba5796dd945ac185fcadffa)
