Fortran: fix checks for STAT= and ERRMSG= arguments of SYNC ALL/SYNC IMAGES
gcc/fortran/ChangeLog:
PR fortran/99351
* match.c (sync_statement): Replace %v code by %e in gfc_match to
allow for function references as STAT and ERRMSG arguments.
* resolve.c (resolve_sync): Adjust checks of STAT= and ERRMSG= to
being definable arguments. Function references with a data
pointer result are accepted.
* trans-stmt.c (gfc_trans_sync): Adjust assertion.
gcc/testsuite/ChangeLog:
PR fortran/99351
* gfortran.dg/coarray_sync.f90: New test.
* gfortran.dg/coarray_3.f90: Adjust error messages.
(cherry picked from commit bbf19f9c20515da9fcd23f08c8139427374e8d77)
