  Log Message:
  -----------
  [TableGen][GlobalISel] Support EXTRACT_SUBREGs for ComplexPattern suboperands.

This makes it possible to write GlobalISel patterns generating
EXTRACT_SUBREG instructions applied to suboperands of ComplexPattern
operands. Currently, TableGen complains that such operands are not
declared in matcher.
