A few helper fragments for loads. e.g. (i8 (load addr:$src)) -> (loadi8 addr:$src). Only to improve readibility.

  This enables the removal of some explicit type casts.

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.)
