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.

Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

fully implemented yet and not used. This is
mainly to clarify that APFloat::mod implements
C fmod, not remainder.

Makes possible to specify options that take multiple arguments (a-la
-sectalign on Darwin). See documentation for details.

instead of requiring all "short description" strings to begin with
two spaces. This makes these strings less mysterious, and it fixes
some cases where short description strings mistakenly did not
begin with two spaces.

since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a
load-and-convert of int 0. Fixes
ieee.exp/mzero[2356].c in gcc testsuite.

by IEEE754, but that seems like a reasonable way
to abstract what happens: information is lost.)

Adding one include file and correct one declaration from class to struct in order to make llvm compile on VC2005.

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.

all the power and risk of fprintf format strings. Use them like this:
OS << format("%10.4f", 42.0) << "\n" << format("%x", 42) << '\n';

and the slow-path cases out of line. This speeds up instcombine
a bit in real world cases. Patch contributed by m-s.
