a99be51bf5 Here is the bulk of the sanitizing.
Almost all occurrences of "bytecode" in the sources have been eliminated.

c9a83e4f19 If an archive is not recognized as an LLVM bytecode archive then declare
that it is native so that the linker will pass it on downstream. This avoids
a problem where the native link line fails because there is both a .so and
a .a file. The .a file gets processed as bytecode and then dropped from the
command line.

3ed469ccd7 For PR786:
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.

be0b356593 PR466:
* 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.

1715ce00e4 Modified the linker so that it always links in an object from an archive
that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.
