[PATCH] D130620: Fix lack of cc1 flag in llvmcmd sections when assertions are enabled

[Aiden Grossman via Phabricator via cfe-commits]

aidengrossman updated this revision to Diff 448152.
aidengrossman marked an inline comment as done.
aidengrossman added a comment.

Added two unit tests to ensure functionality is correct in both
the assertion case and the default case. Should be sufficient
to ensure correct functionality without utilizing regression tests.
However, if regression tests are also desired, let me know and I can
add one in.
