libcilkrts portability


Hi Balaji,

the question was in a different context, but making the code a
bit more portable would be good.

Right now FreeBSD bootstrap is broken due to the following in
runtime/config/x86/cilk-abi-vla.c (and others):

  #include <assert.h>
  #include <stdlib.h>
  #include <stdint.h>
  #ifdef _WIN32
  # define alloca _alloca
  # define INLINE static __inline
  # pragma warning(disable:1025)  // Don't whine about zero extending result of unary operation
  #else
  # include <alloca.h>
  # define INLINE static inline
  #endif

I'm running out of time on my end, but a bit of autoconf-igury and

  # ifdef HAVE_ALLOC_H
  #  include <alloca.h>
  # endif

should heal this.
