This pull includes three independent patch sets, which were
all posted during the 2.4 freeze.
The first is algorithmic improvements to tcg/optimize, both
improving its runtime and its tracking of constants.
The second is improvements to the representation of 32<->64-bit
size changing operations. Still to do here is investigate how
these might be best applied to each tcg host.
The third is improvements to how guest unaligned accesses are
implemented in softmmu mode, for the 4 supported host processors
that themselves implement unaligned accesses.
