Rui Ueyama 1e0b158dbd Add an option to use the MSVC linker to link LTO-generated object files.
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.

Bob Haarman cde5e5b600 refactor COFF linker to use new LTO API
Summary: The COFF linker previously implemented link-time optimization using an API which has now been marked as legacy. This change refactors the COFF linker to use the new LTO API, which is also used by the ELF linker.
