This used to be handled automagically by the option parsing library,
but after LLVM r188314, we should handle it ourselves.

No functionality change, but adds a test.

llvm-svn: 188318

Also change some local variable names: "ti" -> "context" and
"_targetInfo" -> "_context".

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.

llvm-svn: 187534

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

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.

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.

The logic to search a library from the library paths will be implemented
in a different patch.

Fix Driver tests to check return value of parse(), simplify subclassing, and remove unneeded instance variables
