GNU LD has an option named -T/--script which allows a user to specify
a linker script to be used [1]. LLD already accepts linker scripts
without this option, but the option is widely used. Therefore it is
best to support it in LLD as well.

The previous default behavior of LLD is --as-needed. LLD linked
against a DSO only if the DSO file was actually used to link an
executable (i.e. at least one symbol was resolved using the shared
library file.)
In this patch I added a boolean flag to FileNode for --as-needed.
I also added an accessor to DSO name to shared library file class.
