History

Evan Cheng 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.)

IA64

Add some explicit type casts so that tblgen knows the type of the shiftamount, which is not necessarily the same as the type being shifted.

PowerPC

Remove type casts that are no longer needed
