[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 448477.
aidengrossman added a comment.

Rebased against main and adjusted unit tests to check directly
for the cc1 flag in CmdArgs which is directly consumed by the
bitcode writer while creating the .llvmcmd section. Also changed
the flags to better match what is already getting passed in.
