[flang-commits] [flang] [Flang] Assign unittests to flang_compile pool (PR #150041)

[Michael Kruse via flang-commits]

https://github.com/Meinersbur created https://github.com/llvm/llvm-project/pull/150041

#127364 added the FLANG_PARALLEL_COMPILE_JOBS option to limit the number of parallel compilations of Flang sources which require an unusal amount of memory. This patch also adds Flang's unittests to this pool which use about the same amount of memory.
