  Log Message:
  -----------
  [GlobalISel] Disable the indexed loads combine completely unless forced. NFC.

The post-index matcher, before it queries the target legality, walks uses
of some instructions which in pathological cases can be massive. Since
no targets actually support indexed loads yet, disable this to stop wasting
compile time on something which is going to fail anyway.
