This reverts commit r187390 because we should not handle argv's quotes ourselves.

In Windows, unlike Unix, quotes are not processed by the shell. Instead the C
startup routine parses it as described in
http://msdn.microsoft.com/en-us/library/a1y7w461.aspx and pass the results to
main(). So, at the time when the control reaches main(), quotes that should be
removed has already been removed.

We still need to handle quotes in the response file and in .drectve section
ourselves. That will be addressed in different patches.

The BSS atom is similar to the regular defined atom, but it's different
in the sense that it does not have contents. Until now we assumed all the
defined atoms have its contents. That did not fit well to the BSS atom.

The command line option in .drectve section may be quoted by double
quotes, and if that's the case we have to remove them.

This patch removes hacky mangle() function, which strips all decorations
uncondtitionally. LLD now interprets Import Name/Type field in the import
library properly as described in the Microsoft PE/COFF Spec.

Member functions to read the symbol table had too many parameters to propagate
all the temporary information from one to another. By storing the information
to data members, we can simplify the function signatures and improve the
readability.

Some sections, such as with IMAGE_SCN_LNK_REMOVE attribute, is skipped
in the first pass. Such sections need to be skipped in the latter passes.

Missing files will be reported as errors in the later pass, so this patch
does not change the behavior of the LLD linker, but it helps writing unit
tests for the driver.

It's still not as simple as it should be because of the many duplicated
lines, but it's at least better than before.

LLD still accepts both Unix and Windows style options when it's run as
link.exe. This patch does not change functionality.

llvm-svn: 187086

The /include command line option is equivalent to Unix --undefined
option, which forces the linker to resolve the given symbol name
as if it's an unresolved symbol in one of its input files. This feature
is used to link an additional object file or a shared library that no
input files refer to.
