Store merging isn't profitable for the avr. Add a new
effective target keyword "store_merge", and turn it on
only if non_strict_align *and* int32plus, as targets with
smallish word sizes are unlikely to profit from this optimization.

We transform floating point divide instructions to a faster series of
simple instructions, "swdiv".  Currently we do not do that until the
first splitter pass, which is much too late for most optimisations

are not CSEd inside an unrolled loop.  This patch changes things so
those divide instructions are expanded during expand already.
