These fields are for /align option. Section alignment can be set per-section
basis with /section option too. In order to avoid name conflicts, rename the
existing identifiers to become more specific. No functionality change.

/section command line option is to set/reset attributes of the Characteristics
field in the section header. You can set non-default values with this option.
You can make .data section executable with this, for example.

This patch implements the parser of the command line option. The code to use
the parsed values will be committed in a separate patch.

/defaultlib options can be specified implicitly via the .drectve section, and
it's pretty common that multiple object files add the same library, such as
user32.lib, to the input. We shouldn't add the same library multiple times.

Errors in .drectve section were silently ignored. This patch fixes the issue.

intended for debugging and diagnostic output), just inspect the spelling
to check for specific prefixes in drectve section flags.

In addition to being significantly cheaper and not relying on
a debugging interface, this also avoids creating a temporary string and
binding it to StringRef variable. We then went on to access it after the
memory had been deallocated.

This bug too was caught by ASan. I love ASan so much. =]

/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.

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.

/manifestfile:<path> specifies an alternative manifest file output path.
Default is "<output-path>.manifest" where <output-path> is the executable's
path.

The manifest file is an XML file that conveys some information to the loader,
such as whether the executable needs to run as Administrator or not. This patch
is to parse command line option for manifest file.

Actual XML file generation will be done in a separate patch.

Dead-strip root symbols can be undefined atoms, but should not really be
nonexistent, because dead-strip root symbols should be added to initial
undefined atoms at startup. Whenever you look up its name in the symbol
table, some type of atom will always exist.

/defaultlib:foo, is handled properly. Such options were ignored before
