[pstl] OpenMP backend

Hello friends,

I have recently finished the parallel_partial_sort algorithm and I updated to the latest head of main. However, I now have troubles running test on libc++. My command is:

build-debug/bin/llvm-lit -sv libcxx/test/std/pstl --param=compile_flags=’-fopenmp=libomp’

However, the -foenmp=libomp command does not show up on the command line. Consequently, I get errors saying that “omp.h” cannot be found. I have double checked the website documents and this still appears to be the correct invocation.

Any help would be appreciated!
