Rui Ueyama c91f716643 PDB: Add "* Linker *" module.
The added module contains nothing, but it is still useful as a test
to ensure that we are emitting modules that can be read back.

Rui Ueyama 9f66f8277d Re-submit r283825: Add section header stream to PDB.
It was reverted because the change that depends on was reverted.
Now it was submitted as r283925, so we can submit this as well.

Rui Ueyama d381c9842b Add an empty IPI stream.
With this, "llvm-pdbdump yaml -ipi-stream" prints out an IPI stream.
Previously it crashed because it can't handle the case where IPI
stream doesn't exist.

Rui Ueyama ab8e88b686 Remove unused parameter.
I do not fully understand how to use these classes yet, but
seems like these arguments are not used, since without them
all tests still pass. In order to simplify the situation,
I'll remove them now.

Rui Ueyama 3e9d6bbad6 Create FileOutputBuffer lazily.
So that it is clear that FileOutputBuffer does not depend on
PDB file builder. Eventually we will have to to get the file size
info from the file builder to create a file with the exact size.
NFC.

Rui Ueyama b28c6d495d Use functions in DebugInfoPDB to create dummy PDB file.
I don't think we are creating valid PDB file here,
but it is okay because we have never created valid PDBs before.

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.
