Rui Ueyama 1763c0d3bc COFF: Create an empty but valid PDF file.
MSVC linker considers PDB files created with this patch valid.
So you don't have to remove PDB files created by lld before
running MSVC linker.

This patch has no test since llvm-pdbdump dislikes PDB files
with no metadata streams.

Rui Ueyama e737824d8a COFF: Create a PDB file with the correct file signature.
Before this patch, we created an empty PDB file if /debug option is
specified. For MSVC linker, such PDB file is completely broken, and
linker exits without doing anything as soon as it finds an empty PDB
file.

A PDB file created in this patch has the correct file signature.
MSVC linker still thinks that the file is broken, but it then removes
and replaces with its output.

This is an initial patch to support PDB in LLD. We aim to support
PDB in order to make it 100% compatible with MSVC linker. PDB support
is the last missing piece.
