Stop specializing on TARGET_LONG_BITS == 32; unconditionally allocate
a temp and expand with tcg_gen_extu_i32_tl. Split out gen_aa32_addr,
gen_aa32_frob64, gen_aa32_ld_i32 and gen_aa32_st_i32 as separate interfaces.

We already include exec/address-spaces.h and exec/memory.h in
cputlb.c; the include of qemu/timer.h appears to be a fossil.

Rather than defining TARGET_PAGE_BITS to always be 10,
switch to using a value picked at runtime. This allows us
to use 4K pages for modern ARM CPUs (and in particular all
64-bit CPUs) without having to drop support for the old
ARMv5 CPUs which had 1K pages.

Rather than using helpers for physical accesses, use a mmu index.
The primary cleanup is with store-conditional on physical addresses.

The variable parallel_cpus controls the generation of thread aware
atomic code. We only need to set it once we clone our first thread.
At this point any existing translations need to be thrown away.

Some SMBus operations restart the transfer to convert from
write to read mode without an intervening i2c_end_transfer().
The second call cannot fail, so the return code is unchecked,
but this causes Coverity to complain. So add some asserts
and documentation about this.

Force the use of cmpxchg16b on x86_64.
Wikipedia suggests that only very old AMD64 (circa 2004) did not have
this instruction. Further, it's required by Windows 8 so no new cpus
will ever omit it.
If we truely care about these, then we could check this at startup time
and then avoid executing pa
Making these functional rather than object macros will
prevent later problems with complex macro expansion.

Emulating LL/SC with cmpxchg is not correct, since it can
suffer from the ABA problem. Portable parallel code, however,
is written assuming only cmpxchg--and not LL/SC--is available.
This means that in practice emulating LL/SC with cmpxchg is
a viable alternative.
