Removed linking functionality from gccld.cpp and moved it to linker.cpp.
...
Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.

This is effectively a complete rewrite of the globaldce algorithm, resulting
...
in it being both shorter and more effective. It no longer depends on the
callgraph, so one FIXME has been fixed.
Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead. In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.
Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.
