159b0103de Initial commit of an platform-indepdendent implementation for the 
"Program" operating system concept (find and execute programs).

52fa73cde2 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.
Also cleaned up some indentation.

923af3763d Implement the following missing functionality in the PPC backend: 
cast fp->bool
cast ulong->fp
algebraic right shift long by non-constant value
These changes tested across most of the test suite.  Fixes Regression/casts

f7b4fa2e24 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.

8ae92113d6 Now that LiveIntervals::addIntervalsForSpills is fixed, do not require 
LiveVariables.

eb7256be64 Only update LiveVariables if it is available. addIntervalsForSpills 
runs after the initial run of the live interval analysis.

7c06c0aeee 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...

6f0fa9867f 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.

e8fe1becd6 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.
