Subject: [MSSA] Print memory phis when inspecting walker.
X-Git-Tag: upstream/15.0.7~11226
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=50d41f3e0daabdf990465aef70ae6eb626c4e879;p=platform%2Fupstream%2Fllvm.git

This makes the MemorySSA and MemorySSA Walker printers consistent.
Invokation `-print<memoryssa-walker>` should also have the MemoryPhis.
