e5280536a3 When SelectLEAAddr() fails, it shouldn't cause the side effect of having the 
base or index operands being selected.

cbd6ed4d6b For ISD::RET, if # of operands >= 2, try selection the real data dep. operand 
first before the chain.
e.g.
int X;

int foo(int x)
{
  x += X + 37;
  return x;
}

If chain operand is selected first, we would generate:
	movl X, %eax
	movl 4(%esp), %ecx
	leal 37(%ecx,%eax), %eax

rather than
	movl $37, %eax
	addl 4(%esp), %eax
	addl X, %eax

which does not require %ecx. (Due to ADD32rm not matching.)

4172b10ca1 Use new PPC-specific nodes to represent shifts which require the 6-bit 
amount handling that PPC provides.  These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits.  This fixes a miscompilation of crafty with
the new front-end.

3d36a9f6f4 Several things: 
1. Remove redundant type casts now that PR673 is implemented.
2. Implement the OUT*ir instructions correctly.  The port number really
   *is* a 16-bit value, but the patterns should only match if the number
   is 0-255.  Update the patterns so they now match.
3. Fix patterns for shifts to reflect that the shift amount is always an
   i8, not an i16 as they were believed to be before.  This previous fib
   stopped working when we started knowing that CL has type i8.
4. Change use of i16i8imm in SH*ri patterns to all be imm.
