handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently. Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.
Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality. I have removed
such blocks for the appropriate targets in this patch.

MADD was not correctly writing to HI.
MSUB/MSUBU are specified as `HI||LO - product', not `product - HI||LO'.

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.
Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.
Big/Little endian is not handled because devices should not know or care
about this to start with.

Include assert.h from qemu-common.h and remove other direct uses.
cpu-all.h still need to include it because of the dyngen-exec.h hacks

This reverts commit r7127, r7132 is a better fix for that.

There is no need to exit the tb after a call to helper_raise_exception
as it already calls cpu_loop_exit().

check_*() functions may in fine call generate_exception(), which ends
by a call to tcg_gen_exit_tb(). As a consequence, we have to make sure
that no TCG temp variables are crossing a check_*() function.

Use a consistent naming of arguments and TCG variables across the whole
file, the same as in tcg/tcg-op.h:
- arg1, arg2, ... for arguments
- t0, t1, t2, ... for variables

CPU state should also be saved for helpers that in fine call
cpu_unlink_tb(). Reported by Stefan Weil.

This replaces a compile time option for some targets and adds
