For a 64-bit host, the high bits of a register after a 32-bit operation
are undefined. Adjust the temps mask for all 32-bit ops to reflect that.

If the align option is enabled, we print to the user whenever
the guest clock is behind the host clock in order for he/she
to have a hint about the actual performance. The maximum
print interval is 2s so as not to spam the console.

The icount option already implemented in QEMU allows the guest to run at a
theoretical
frequency of 1/(2^N) GHz (N is the icount parameter). The goal of this patch is
to have a
real guest frequency close to the one imposed by using the icount option.
The main idea behind the algorithm is that
The align option is used for activating the align algorithm
in order to synchronise the host clock and the guest clock.
Therefore we slightly modified the existing icount option.
Thus, the new way to specify an icount is
'-icount [icount=][N|auto][,align]'

The ppc32 backend isn't getting much love and attention recently, with
all of the improvements coming from me into the ppc64 backend. Let's
reduce the maint burden a bit and combine them.
This does have a few other patches that are not strictly related to the
merge of the backends, such as
Rather than using tcg_out32 and opcodes directly. This allows us
to remove LD_ADDR and CMP_L macros.
