x86 systems run their romstage as execute-in-place from flash, which
prevents them from having writable data segments. In several code pieces
that get linked into both romstage and ramstage, this has been worked
around by using a local variable and having the 'static' storage class
guarded by #ifndef __PRE_RAM__.
However, x86 is the only architecture using execute-in-place (for now),
so it does not make sense to impose the restriction globally. Rather
than fixing the #ifdef at every occurrence, this should really be
wrapped in a way that makes it easier to modify in a single place. The
chromeos/cros_vpd.c file already had a nice approach for a wrapper
macro, but unfortunately restricted it to one file... this patch moves
it to stddef.h and employs it consistently throughout coreboot.
BRANCH=nyan
BUG=None
TEST=Measured boot time on Nyan_Big before and after, confirmed that it
gained 6ms from caching the FMAP in vboot_loader.c.

It's not a SPI related macro, hence move it to stddef.h where
other similar macros live.

This patch adds a new static assertion macro that can be used to check
the offsets in structures that overlay register sets at compile time. It
uses the _Static_assert() declaration from the new ISO C11 standard,
which is supported (even without -std=c11) by GCC after version 4.6.
(There is supposedly also support in clang, although I haven't tried
it... let's deal with compiler issues when/if they turn up.)
I've added it to all structures for our current ARM SoCs for now, and I
think every new register overlay we add going forward should use them
(at least for the last member, but feel free to add more if you think
it's useful).

In the process of getting rid of compiler includes during in coreboot
and libpayload, we defined size_t and ssize_t ourselves, using a GCC
macro for size_t: __SIZE_TYPE__. Unfortunately, there is no
__SSIZE_TYPE__, so we temporarily redefine unsigned to signed to make
__SIZE_TYPE__ __SSIZE_TYPE__.

stddef.h should be fairly generic across all platforms we'd want to
support, so let's move it to generic code.
