[GlobalISel] Add commutative matchers for compares.
This adds:
* `m_c_GICmp`
* `m_c_GFCmp`
These work the same way as the standard matchers, but will also try to commute
the LHS and RHS of a compare to get a match.
E.g.
```
m_c_GICmp(m_Pred(...), m_GAdd(...), m_GSub(...))
```
Can match either of
```
icmp cc (add x, y), (sub a, b)
icmp swapped_cc (sub a, b), (add x, y)
```
