32-bit ABIs support passing 64-bit integers by registers via argument
translation. Commit 59c10c52f573 ("riscv: compat: syscall: Add
compat_sys_call_table implementation") implements the compat_arg_u64
macro for efficiently defining little endian compatibility syscalls.
Architectures supporting big endianness may benefit from reciprocal
argument translation, but are welcome also to implement their own.

compat: make linux/compat.h available everywhere
Parts of linux/compat.h are under an #ifdef, but we end up
using more of those over time, moving things around bit by
bit.
To get it over with once and for all, make all of this file
uncondititonal now so it can be accessed everywhere. There
are only a few types left that are in asm/compat.h but not
yet in the asm-generic version, so add those in the process.
This requires providing a few more types in asm-generic/compat.h
that were not already there. The only tricky one is
compat_sigset_t, which needs a little help on 32-bit architectures
and for x86.

asm-generic: Move common compat types to asm-generic/compat.h
While converting compat system call handlers to work on 32-bit
architectures, I found a number of types used in those handlers
that are identical between all architectures.
Let's move all the identical ones into asm-generic/compat.h to avoid
having to add even more identical definitions of those types.
For unknown reasons, mips defines __compat_gid32_t, __compat_uid32_t
and compat_caddr_t as signed, while all others have them unsigned.
This seems to be a mistake, but I'm leaving it alone here. The other
types all differ by size or alignment on at least on architecture.
compat_aio_context_t is currently defined in linux/compat.h but
also needed for compat_sys_io_getevents(), so let's move it into
the same place.
While we still have not decided whether the 32-bit time handling
will always use the compat syscalls, or in which form, I think this
is a useful cleanup that we can merge regardless.

time: Add an asm-generic/compat.h file
We have a couple of files that try to include asm/compat.h on
architectures where this is available. Those should generally use the
higher-level linux/compat.h file, but that in turn fails to include
asm/compat.h when CONFIG_COMPAT is disabled, unless we can provide
that header on all architectures.
This adds the asm/compat.h for all remaining architectures to
simplify the dependencies.
Architectures that are getting removed in linux-4.17 are not changed
here, to avoid needless conflicts with the removal patches. Those
architectures are broken by this patch, but we have already shown
that they have no users.
