More important than any performance concerns, the code was dropping the
temporary string on the floor after assigning it to a StringRef, and
then used the StringRef later. Caught by running the LLD tests under
ASan.

On discussing this with Nick, it looks like the StubAtoms
that contain a lazyImmediate reference kind should be null
and the location needs to be fixed up later with some value
that is an offset into the __LINKEDIT segment.

The drawback is that it allows yaml files with references
that expect a target to be considered without one.

This results in bad yaml files that would need to be handled
in the YAML Reader.

Inorder to fix this, the Stub Atoms use a dummy target such
as itself.

/merge:<from>=<to> option makes the linker to combine "from" section to "to"
section. This patch is to parse the option. The actual feature will be
implemented in a subsequent patch.

We really need a test for the manifest file output, but because it depends
on external commands (CVTRES.EXE and RC.EXE), it's not very easy to write it.

The internal byte array of the SmallString filled by createTemporaryFile() is
not guaranteed to be NUL-terminated. We need to call c_str() to handle it
safely.

Disable tests to be run with REQUIRES: disable. Note disable is not added to the
config by the test runner Mkaefiles, so essentially disables the test.

Instead of making the linker to create a manifest XML file in the same
directory as the resulting binary, you can embed the XML as a part of
resource into the executable.

In order to do that, the linker first creates a resource script file containing
the XML file, compile it into a binary resource file with RC.EXE, and then
convert it to a COFF file with CVTRES.EXE.

This patch won't change LLD's behavior because it's a temporary file and
LLD does not use the file extension to determine file type. But using the
correct file extension is a good thing.
