541ed9fd02 Do not use host floating point types when emitting 
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.

ed6af24e14 Make special cases (0 inf nan) work for frem. 
Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

24b66a83ca Add an IEEE remainder function, which is not 
fully implemented yet and not used.  This is
mainly to clarify that APFloat::mod implements
C fmod, not remainder.

b8cab9227a Fix command-line option printing to print two spaces where needed,

begin with two spaces.

944fac71e0 Switch the asmprinter (.ll) and all the stuff it requires over to 
use raw_ostream instead of std::ostream.  Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).

Other interesting changes:
 1) This makes Value::print be non-virtual.
 2) AP[S]Int and ConstantRange can no longer print to ostream directly, 
    use raw_ostream instead.
 3) This fixes a bug in raw_os_ostream where it didn't flush itself 
    when destroyed.
 4) This adds a new SDNode::print method, instead of only allowing "dump".


A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream 
versions.

This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.
