a8911f33f8 Factor out a large amoutn of the cast handling code in fast isel into helper methods. 
This simultaneously makes the code simpler and adds support for sext as well.

5fef19facf Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy requested 
was inserted or not.  This allows bitcast in fast isel to properly handle the case
where an appropriate reg-to-reg copy is not available.

909c1c36e2 Added "str()" method to raw_string_ostream. 
str() mirrors the same method in std::ostringstream.
str() flushes the buffered stream contents to string and returns a reference to the string.

type down.  This is not currently used.

af40013b25 we should use 'class' for non-pod types instead of 'struct' to 
make it easier to deal with the VC++ struct/class bug.

b09962fd1a get MachineConstantPool off std::ostream, onto raw_ostream. It would be 
really nice if someone converted MachineFunction::print to raw_ostream.

fe3155fc62 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.

b7914ec04e add a simple mechanism for formatted output. This gives raw_ostream's 
all the power and risk of fprintf format strings.  Use them like this:

  OS << format("%10.4f", 42.0) << "\n" << format("%x", 42) << '\n';

a9d5f9b006 Move the point at which FastISel taps into the SelectionDAGISel 
process up to a higher level. This allows FastISel to leverage
more of SelectionDAGISel's infastructure, such as updating Machine
PHI nodes.

Also, implement transitioning from SDISel back to FastISel in
the middle of a block, so it's now possible to go back and
forth. This allows FastISel to hand individual CallInsts and other
complicated things off to SDISel to handle, while handling the rest
of the block itself.

To help support this, reorganize the SelectionDAG class so that it
is allocated once and reused throughout a function, instead of
being completely reallocated for each block.

a398d11527 Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.
