Simon Pilgrim b2f83027f4 [DAG] Match USUBSAT patterns through zext/trunc 
This patch handles usubsat patterns hidden through zext/trunc and uses the getTruncatedUSUBSAT helper to determine if the USUBSAT can be correctly performed in the truncated form:

zext(x) >= y ? x - trunc(y) : 0 --> usubsat(x,trunc(umin(y,SatLimit)))
zext(x) >  y ? x - trunc(y) : 0 --> usubsat(x,trunc(umin(y,SatLimit)))

Based on original examples:

void foo(unsigned short *p, int max, int n) {
    int i;
    unsigned m;
    for (i = 0; i < n; i++) {
        m = *--p;
        *p = (unsigned short)(m >= max ? m-max : 0);
    }
}
