Patch by Scott Michel.

Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

"clean" target item. This gets around having the built sources disappear
when only one build mode wants to be cleaned. With the "clean-all" target,
all build modes are cleaned so it also makes sense to clean out the built
sources at that point.

a directory's Makefile will prevent the build products from that directory
from being installed. This is useful for tools and libraries that are
only useful as part of the build process.

libraries linked with. This permits a project to still use USEDLIBS to
specify its own libraries in conjunction with LINK_COMPONENTS. llvm-stacker
needs this after libLLVMTransforms.a went away.

updated.

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.

Close out this long standing bug by removing the remaining overloaded
virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

makefile can handle an empty definition for BISON variable.
