Create a link from $BUILD_OBJ_ROOT/lib/System/platform to
$BUILD_SRC_ROOT/lib/System/$build which gives us the ability to
configure the lib/System for the current type of operating system.

Revise the design of the Path concept per peer review. Too many changes to
note individually but these essence of it is to not derive from
std::string, clarify the interface, and provide better documentation.
There is now also (untested) implementations for AIX, Darwin, and SunOS.

Back out this change as it broke the build last night. This should be
investicated further as the linearscan variants don't really need
LiveVariables...

Add the CompactionTableIsEmpty function so that we can determine if a
CompactionTable really needs to be emitted. This is not a straight forward
computation, hence the need for a member function here.

Add default index functor (an identity functor). You could use a
