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 :)

450fcb1d91 (store (op (load ...)), ...) 
If store's chain operand is load, then use load's chain operand instead. If
it isn't (likely a TokenFactor), then do not allow the folding.

c3d295a47c If we want to emit things in enum order, use getInstructionsByEnumValue to 
get the order, don't compute it ourselves.

Don't emit stuff like (14<<0), emit 14 instead.

Don't attempt to get target properties for builtin instructions.

8b6fb0763c Another folding problem: if a node r/w chain or flag, don't fold it if it 
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.

849d522805 Incoming (and optional) flag bugs. They may be embedded inside a inner node of 
a pattern. Also, nodes which take incoming flag should not be folded if it has

d3713a9b9a Prevent folding of a node with multiple uses if the node already folds a load! 
Here is an example where the load ended up being done twice:

%A = global uint 0

uint %test(uint %B, ubyte %C) {
	%tmp = load uint *%A;
	%X = shl uint %tmp, ubyte %C
	%Cv = sub ubyte 32, %C
	%Y = shr uint %B, ubyte %Cv
	%Z = or uint %Y, %X
	store uint %Z, uint* %A
	ret uint %Z
}

==>

	subl $4, %esp
	movl %ebx, (%esp)
	movl 8(%esp), %edx
	movl A, %eax
	movb 12(%esp), %bl
	movb %bl, %cl
	shldl %cl, %edx, %eax
	movb %bl, %cl
	shldl %cl, %edx, A
	movl (%esp), %ebx
	addl $4, %esp
	ret

f168c680e5 Use pattern information to determine whether the use expects this 
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.

7b8f8c317e * Remove instruction fields hasInFlag / hasOutFlag and added SNDPInFlag and 
SNDPOutFlag to DAG nodes. These properties do not belong to target specific
instructions.
* Added DAG node property SNDPOptInFlag. It's same as SNDPInFlag except it's
optional. Used by ret / call, etc.

8c5173a440 Tblgen was generating syntactically illegal C++ code like: 
SDOperand Tmp0,Tmp1,Tmp2,Tmp3,;

GCC has a bug (24907) in which is fails to catch this, but VC++ correctly
notes its illegality, so tblgen must be taught to only generate legal C++.
