OpenMP prohibits privatisation of variables that appear in expressions for statement functions. This is a re-working of an old patch https://reviews.llvm.org/D93213 by @praveen-g-ctt. The old patch couldn't be landed because of ordering concerns. Statement functions are rewritten during parse tree rewriting, but this was done after resolve-directives and so some array expressions were incorrectly identified as statement functions. For this reason **I have opted to re-order the semantics driver so that resolve-directives is run after parse tree rewriting**.
