Add a version of AsmPrinter::EOL that takes a const char* so that we don't have to do as many implicit std::string constructions.
Unfortunately, this doesn't appear to translate to a real speedup in practice.

  - Use a more accurate heuristic for the size of the hashtable.
  - Use bitwise and instead of modulo since the size is a power of two.
  - Use new[] instead of malloc().

This fixes PR2503, though we should also fix other passes not to emit this kind of code.

the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.
