	macros, moved from mini.

	* sgen-gc.c: Take a thread's stack top and registers from the
	sigcontext in the suspend signal handler.

	* sgen-gc.h, sgen-archdep.h, Makefile.am: Move arch-dependent
	stuff to sgen-archdep.h.

	* gc.c, gc-internal.h: Remove the get_ip_from_sigctx installer and
	caller, because have code in sgen-archdep.h to acquire that data.

	* mini.c: get_ip_from_sigctx installer has been removed, so don't
	call it anymore.

	* mini-x86.h, mini-amd64.h, mini-ppc.h: UCONTEXT macros moved (to
	utils/mono-sigcontext.h).

	* exceptions-amd64.c: Use the UCONTEXT_GREGS macro instead of an
	#ifdef.
