  Log Message:
  -----------
  [GlobalISel] Add and use a m_GAddLike pattern matcher. NFC (#125435)

This adds a Flags parameter to the BinaryOp_match, allowing it to detect
different flags like Disjoint. A m_GDisjointOr is added to detect Or's
with disjoint flags, and G_AddLike is then either a m_GADD or
m_GDisjointOr.

The rest is trying to allow matching `const MachineInstr&`, as opposed
to non-const references.
