[lld] r286921 - Identify object files compiled with cl.exe /GL.

[Rui Ueyama via llvm-commits]

Author: ruiu

New Revision: 286921

URL: http://llvm.org/viewvc/llvm-project?rev=286921&view=rev
Log:
Identify object files compiled with cl.exe /GL.

Object files compiled with cl.exe /GL contain intermediate code for LTO.
We can't (and don't want to) interpret such code, but we should print
out a user-friendly error message.
