Add __asm __volatile("":::"memory") at a critical point in alloc.c.
gcc thinks it knows the semantics of malloc and so it thinks it can
optimize out the manipulation of __malloc_hook; however, doing so causes
the subsequent malloc call to come back to itself, leading to an infinite
recursion and SIGSEGV in temacs.
This fixes the remaining part of PR 45669.
Someone(TM) should check if this issue affects other Emacs versions
