+Subject: [PATCH] Reland [clang] Disable autoupgrading debug info in ThinLTO
+ builds
+
+ThinLTO reads bitcode many times and attempts to upgrade the debug info every time. This is expensive since it calls the verifier. We don't need this given all LLVM bitcode producers are from the same version of LLVM.
+
+For just the build step that runs ThinLTO and links official Chrome, measured 34T -> 32T instructions via perf stat.
+
+Reland disables adding flag for ChromeOS since that toolchain is too old to have this flag.
+
