Ensure that C99 macros are defined regardless of the inclusion order of
headers in vixl. This is required at least on NetBSD.

The vixl/globals.h headers defines __STDC_CONSTANT_MACROS and must be
included before other system headers.

This file defines unconditionally the following macros, without altering
the original sources:
 - __STDC_CONSTANT_MACROS
 - __STDC_LIMIT_MACROS
 - __STDC_FORMAT_MACROS
