Jean Perier 7c158e3e55 [flang] add evaluate::IsAllocatableDesignator helper ... Previously, some semantic checks that are checking if an entity is an allocatable were relying on the expression being a designator whose last symbol has the allocatable attribute. This is wrong since this was considering substrings and array sections of allocatables as being allocatable. This is wrong (see NOTE 2 in Fortran 2018 section 9.5.3.1). Add evaluate::IsAllocatableDesignator to correctly test this. Also add some semantic tests for ALLOCATED to test the newly added helper. Note that ifort and nag are rejecting coindexed-named-object in ALLOCATED (`allocated(coarray_scalar_alloc[2])`). I think it is wrong given allocated argument is intent(in) as per 16.2.1 point 3. So 15.5.2.6 point 4 regarding allocatable dummy is not violated (If the actual argument is a coindexed object, the dummy argument shall have the INTENT (IN) attribute.) and I think this is valid. gfortran accepts it. The need for this helper was exposed in https://reviews.llvm.org/D122779.
