Implement support for converting to string at "natural precision", and fix some

major bugs in long-precision conversion.

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.

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).

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.

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.
