of it more cleanly.  Double the size of OpActions, allowing it to hold actions
for any VT.

57b2492ecc Make ConstantFP legalize into TargetConstantFP like other leaf nodes do. Allow 
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.

024ea8e7ca 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))) {

GCC not jump-threading across this common code, and produces far nicer
output.

3cdfba635c 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.

b6fc7b5e71 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 :)
