      Description

      JDK-8190308 introduced a function using MAP_NORESERVE flag on mmap(). But this is not specified in POSIX[1]. So move this flag out of os_posix.cpp.

      In addition, move MAP_ANONYMOUS as well since this is also not specified.

      Currently AIX is the only OS reporting this problem.
