Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=44733 | TEST 'libomp :: ompt/synchronization/reduction/tree_reduce.c' FAILED on 32-bit x86 ]] For 32-bit we need at least 3 variables to avoid atomic reduction to be choosen by runtime function `__kmp_determine_reduction_method`. This patch adds reduction variables to the testcase. Reviewers: mgorny, Hahnfeld Differential Revision: https://reviews.llvm.org/D73850
