[flang] Checks for constraints C731 through C740

In most cases, I just added the contraint names to the code and tests.

I implemented the following checks:
  - C736 A child type with a coarray ultimate component must have a parent with
    a coarray ultimate component.
  - C737 A child type with and EVENT_TYPE or LOCK_TYPE component must have a
    parent either which is EVENT_TYPE or LOCK_TYPE or a type with an EVENT_TYPE
    or LOCK_TYPE component.
  - C740 Sequence types must contain at least on component
  - C740 Data components of sequence types must either be of an intrinsic type
    or a sequenced derived type.

After implementing these checks, some tests had new errors unrelated to their
original purpose, so I fixed them.
