8e66595512 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.

ca5d1c378c Now that LiveIntervals::addIntervalsForSpills is fixed, do not require 
LiveVariables.

d8d26b3268 Only update LiveVariables if it is available. addIntervalsForSpills 
runs after the initial run of the live interval analysis.

ccdf21af1f 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...

5501e568b3 Add default index functor (an identity functor). You could use a 
vector directly to get the same functionality but using a DenseMap
makes the code more readable IMO.
