079b6f5ee5 Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are 
mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.

major bugs in long-precision conversion.

c883ad2dd8 Move the two definitions of operator<< into namespace llvm, so they 
will be found by argument-dependent lookup. As with the previous
commit, GCC is allowing ill-formed code.

e4d4c43cc8 Define the new operator<< for sets into namespace std, so that 
argument-dependent lookup can find it. This is another case where an
LLVM bug (not making operator<< visible) was masked by a GCC bug
(looking in the global namespace when it shouldn't).

003a09c68d Substantially optimize APFloat::toString() by doing a single large divide to 
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.

00e65de9d8 Add accessors for the largest-magnitude, smallest-magnitude, and 
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.

04b091a782 handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a 
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.

8047d9a6be move an optimization for memcmp out of simplifylibcalls and into 
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.
