Pass CPU string to LTO pipeline. Previously an empty CPU string was passed to the LTO engine which resulted in a generic CPU for which certain features like NOPL were disabled. This fixes that. Patch by Pratik Bhatu! llvm-svn: 323801

Fix lit substitution in test. There is no '%m' substitution, so a literal "%m.so" file was being generated in the source tree. llvm-svn: 323820
