New Revision: 336869

URL: http://llvm.org/viewvc/llvm-project?rev=336869&view=rev
Log:
IR: Skip -print-*-all after -print-*

This changes `-print-*` from transformation passes to analysis passes so
that `-print-after-all` and `-print-before-all` don't trigger.  This
avoids some redundant output.

Patch by Son Tuan Vu!
