[Andy Kaylor via llvm-commits]

andrew.w.kaylor updated this revision to Diff 53059.
andrew.w.kaylor added a comment.

-Rebased
-Added new unskippable passes (Bitcode Writer and pseudo instruction expansion for ARM and AArch64)
-Added a test to verify code generation works with all skippable passes skipped
-Minor updates to make tests less flaky
