[PATCH] D29526: Add an option to use the MSVC linker to link LTO-generated object files.

[Rui Ueyama via Phabricator via llvm-commits]

This patch defines a new command line option, /MSVCLTO, to LLD.
If that option is given, LLD invokes link.exe to link LTO-generated
object files. This is hacky but useful because link.exe can create
PDB files.
