[PATCH] D61022: [ThinLTO] Pass down opt level to LTO backend and handle -O0 LTO in new PM

[Mehdi AMINI via Phabricator via cfe-commits]

mehdi_amini added inline comments.

Comment at: llvm/test/tools/gold/X86/opt-level.ll:53
+  ; CHECK-O1-OLDPM: select
+  ; The new PM does not do as many optimizations at O1
+  ; CHECK-O1-NEWPM: phi
----------------
This is intended? I'm surprised the two PMs don't have the same list of passes for a given opt level?
