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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8
