major bugs in long-precision conversion.

cut the significand down to the desired precision *before* entering the
core divmod loop.  Makes the overall algorithm logarithmic in the exponent.

There's still a lot of room for improvement here, but this gets the
performance back down to acceptable-for-diagnostics levels, even for
long doubles.
negligible, even on long doubles.

smallest-normalized-magnitude values in a given FP semantics.
Provide an APFloat-to-string conversion which I am quite ready to admit could
be much more efficient.

order should be immune to such problems.

compare.  On other targets we end up with a call to memcmp because we don't
want 16 individual byte loads.  We should be able to use movups as well, but
we're failing to select the generated icmp.

SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.
