Mark negative-zero-to-int conversion as Inexact,2008-10-07T00:40:01ZDale Johannesendalej@apple.com2008-10-07T00:40:01Zurn:sha1:e4a424590675cf32b729420665626774b01b114d
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.

Be more precise about which conversions of NaNs2008-10-06T22:59:10ZDale Johannesendalej@apple.com2008-10-06T22:59:10Zurn:sha1:2df5eec2ff25cbb7e5fd4848e667fb9f854d3339
are Inexact. (These are not Inexact as defined
by IEEE754, but that seems like a reasonable way
to abstract what happens: information is lost.)

Switch the asmprinter (.ll) and all the stuff it requires over to2008-08-23T22:23:09ZChris Lattnersabre@nondot.org2008-08-23T22:23:09Zurn:sha1:944fac71e082cc2664cc71b4d3f6c72bab7143fb
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.
