0189197608 Before implementing copyfromreg, we'll implement copytoreg correctly. 
This gets us this for the previous testcase:

_test:
        lis r2, 0
        ori r3, r2, 65535
        blr

Note that we actually write to r3 (the return reg) correctly now :)

4ccd406317 Now that we have operand info for machine instructions, use it to create 
temporary registers for things that define a register.  This allows dag->dag
isel to compile this:

int %test() { ret int 65535 }

into:

_test:
        lis r2, 0
        ori r2, r2, 65535
        blr

Next up, getting CopyFromReg to work, allowing arguments and cross-bb values.

2d973e45b8 Implement the first chunk of a code emitter. This is sophisticated enough to 
codegen:

but can't do anything more (yet). :)

495a0b5191 Add a new beta option for critical edge splitting, to avoid a problem that 
Nate noticed in yacr2 (and I know occurs in other places as well).

This is still rough, as the critical edge blocks are not intelligently placed
but is added to get some idea to see if this improves performance.

6269ed125f Added generic code expansion for [signed|unsigned] i32 to [f32|f64] casts in the 
legalizer.  PowerPC now uses this expansion instead of ISel version.

Example:

// signed integer to double conversion
double f1(signed x) {
  return (double)x;
}

// unsigned integer to double conversion
double f2(unsigned x) {
  return (double)x;
}

// signed integer to float conversion
float f3(signed x) {
  return (float)x;
}

// unsigned integer to float conversion
float f4(unsigned x) {
  return (float)x;
}

d5d0f9bd20 Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef) 
used to tack a register number onto the node.

Instead of doing this, make a new node, RegisterSDNode, which is a leaf
containing a register number.  These three operations just become normal
DAG nodes now, instead of requiring special handling.

Note that with this change, it is no longer correct to make illegal
CopyFromReg/CopyToReg nodes.  The legalizer will not touch them, and this
is bad, so don't do it. :)

Teach the legalizer to promote FP_TO_UINT to FP_TO_SINT if the wider
  FP_TO_UINT is also illegal.  This allows us on PPC to codegen

32c392a3a5 Fix the fabs regression on x86 by abstracting the select_cc optimization 
out into SimplifySelectCC.  This allows both ISD::SELECT and ISD::SELECT_CC
to use the same set of simplifying folds.

e5d63829fd Some SELECT_CC cleanups: 
1. move assertions for node creation to getNode()
2. legalize the values returned in ExpandOp immediately
3. Move select_cc optimizations from SELECT's getNode() to SELECT_CC's,
   allowing them to be cleaned up significantly.

This paves the way to pick up additional optimizations on SELECT_CC, such
as sum-of-absolute-differences.

7cf7e3f33f Eliminate the SetCCSDNode in favor of a CondCodeSDNode class. This pulls the 
CC out of the SetCC operation, making SETCC a standard ternary operation and
CC's a standard DAG leaf.  This will make it possible for other node to use
CC's as operands in the future...

82299e7097 Change FindEarliestCallSeqEnd (used by libcall insertion) to use a set to 
avoid revisiting nodes more than once.  This eliminates a source of
potentially exponential behavior.  For a small function in 191.fma3d
(hexah_stress_divergence_), this speeds up isel from taking > 20mins to
taking 0.07s.
