Subject: [PATCH] [flang] `do concurrent`: Enable delayed localization by
 default

Enables delayed localization by default for `do concurrent`. Tested both
gfortran and Fujitsu test suites.

All tests pass for gfortran tests. For Fujitsu, enabled delayed
localization passes more tests:

Delayed localization disabled:
Testing Time: 7251.76s
  Passed            : 88520
  Failed            :   162
  Executable Missing:   408

Delayed localization enabled:
Testing Time: 7216.73s
  Passed            : 88522
  Failed            :   160
  Executable Missing:   408
