Subject: [PATCH] Add 'libgomp.c-c++-common/pr100059-1.c'

For nvptx offloading, it'll FAIL its execution test until nvptx-tools updated
to include commit 1b5946d78ef5dcfb640e9f545a7c791b7f623911
"Merge commit '26095fd01232061de9f79decb3e8222ef7b46191' into HEAD [#29]",
<https://github.com/MentorEmbedded/nvptx-tools/commit/1b5946d78ef5dcfb640e9f545a7c791b7f623911>.
