This is done at call-site and does not need to be handled in __kmp_invoke_microtask. It was already absent from the x86 and x86_64 assembly, this patch removes it from the generic implementation in z_Linux_util.cpp and adds documentation for AArch64 and PPC64 that it's actually not needed. I can't test on these architectures, so I don't want to change the code just because it looks right :) While at it, rename some variables for consistency and add a check in test/ompt/parallel/normal.c that the pointer was reset before entering the barrier.
