Very very humble beginnings of IR
Make visitor accept Object so IR Builder can use that parameter
disable travis here for now
visitor returns value to eliminate needing a stack
Make every node throw at first
Comment out Jasmine for now since JI is booched on this branch already
Add compile.mode=IR which still runs nothing
Still nothing running but a tiny step closer
Unhooked introduction to instructions
Add first real operand
Merge with master
Remove bogus print statement
Add back executioncontext signatures so JIT partially runs
download rhino for a benchmark run
Merging with master to pull in --ast
Sketch in bare minimum variables operands
Some more IR Sketching
Sketch in IR Temporary variables
Still not running most basic of basic but beginnings of very naive IR interp
IR CFG sketching. Use brand new dirgra from JRuby project
