Compiling this program was causing a crash, but it seems to be recently that it started hitting the assertion.

[Flang][OpenMP] Add restriction about subobjects to firstprivate and … (
0661af8 
#89608)

…lastprivate

OpenMP 5.2 standard (Section 5.3) defines privatization for list items.
Section 3.2.1 in the standard defines list items to exclude variables
that are part of other variables.

This patch adds the restriction to firstprivate and lastprivates, it was
previously added for privates.

Fixes #67227

Note: The specific checks that are added here are explicitly called out
in OpenMP 4.0
(https://www.openmp.org/wp-content/uploads/OpenMP4.0.0.pdf) Sections
2.14.3.4 and 2.14.3.5 but in later standards have become implicit
through other definitions.

Consider the following: ```console $ cat task_invalid.f90 program p integer :: a(10) 
!$omp task firstprivate(a(3))
    continue
!$omp end task

!$omp taskwait
