improve code insertion in two ways:
1. Only forward subst offsets into loads and stores, not into arbitrary
things, where it will likely become a load.
2. If the source is a cast from pointer, forward subst the cast as well,
allowing us to fold the cast away (improving cases when the cast is
from an alloca or global).
This hasn't been fully tested, but does appear to further reduce register
pressure and improve code. Lets let the testers grind on it a bit. :)

Fix the #1 code quality problem that I have seen on X86 (and it also affects

struct Vector3 { double x, y, z; };
struct Matrix3 { Vector3 a, b, c; };
double dot(Vector3 &a, Vector3 &b) {
return a.x * b.x + a.y * b.y + a.z * b.z;

Vector3 mul(Vector3 &a, Matrix3 &b) {
Vector3 r;
r.x = dot( a, b.a );
r.y = dot( a, b.b );
r.z = dot( a, b.c );
return r;
}
void transform(Matrix3 &m, Vector3 *x, int n) {
for (int i = 0; i < n; i++)
x[i] = mul( x[i], m );
}
we compile transform to a loop with all of the GEP instructions for indexing
into 'm' pulled out of the loop (9 of them). Because isel occurs a bb at a time
we are unable to fold the constant index into the loads in the loop, leading to
PPC code that looks like this:
LBB3_1: ; no_exit.preheader

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.

This is a bugfix for SelectNodeTo. In certain situations, we could be
selecting a node and use a mix of getTargetNode() and SelectNodeTo. Because
SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert
