e3bd778e4d Clean up the interface to ValueTypeActions, allowing Legalize to use a copy
of it more cleanly.  Double the size of OpActions, allowing it to hold actions
for any VT.

targets to register custom legalizers for ConstantFP in case there isn't a
fixed list of constants that can be generated.  On some architectures (ia64?)
all fp immediates are legal.

24e00a4ac1 Emit series of conditionals with &&, emitting stuff like this:
if (N1.getOpcode() == ISD::LOAD &&
        N1.hasOneUse() &&
        !CodeGenMap.count(N1.getValue(0)) &&
        !CodeGenMap.count(N1.getValue(1))) {

instead of this:

    if (N1.getOpcode() == ISD::LOAD) {
      if (N1.hasOneUse()) {
        if (!CodeGenMap.count(N1.getValue(0))) {
          if (!CodeGenMap.count(N1.getValue(1))) {

67a202bc42 now that we have control over emission of the code, emit the code using nested
"if" statements (indenting it appropriately, of course) instead of using goto's.

This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

8a0604b523 Change PatternCodeEmitter to emit code into a buffer instead of emitting it
directly to the output file.  This makes things simple because the code doesn't
have to worry about indentation or the case when there is no goto.  It also
allows us to indent the code better without touching everything :)

c52ad4f04e Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it
faster.  This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).

It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change.  Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.

This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.
