Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

With these patches we implement the ability for the Linker library to
keep track of which libraries were actually bytecode files (not archives)
and cause their users to remove such files from the list of libraries to
pass to the native linker.

the module being constructed. This is used to correctly name the module.
Previously the name of the linker tool was used which produces confusing
output when the module identifier is used in an error message.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set
Changes pass Dejagnu and llvm-test/SingleSource tests.

using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*.

* Fix loop style per standards
* Don't create a new Module when the Linker's module is released.
* Add/fix function comments.

correctly link globals whose LLVM types do not match.
This fixes several of the F2C SPEC FP benchmarks, which were failing this
due to the implementation of common blocks used by f2c.

* Make the linker find lib*.bca files now instead of lib*.bc since those
are what the makefiles now generate for bytecode archives.
* Make sure the linker only links archives when LinkLibraries is called.
Previously if it found a lib*.bc file and that file was a bytecode file,
it would link in the entire bytecode. This could make -lc -lc fail with
duplicate symbols error but it shouldn't as searching multiple libraries,
even the same one more than once, is permitted.
* Now that the above problems are corrected, implement the dependent libs
feature. After the module is linked with all specified libraries, the
LinkLibraries function will obtain the set of dependent libraries from
the linked modules and attemp to find and link against those libraries.
