Upstream analysis fix
Review Request #2312 - Created June 2, 2015 and submitted
|benjyw, davidt, fkorotkov, tejal|
This is just the analysis fix from r/2155, without the additional analysis checks (since they've probably outlived their usefulness at this point anyway.)
- Creates contexts for all targets rather than just targets within a particular chunk. This makes analysis from previously compiled chunks (for the current language, at least) available to zinc.
- Adds debug logging when analysis is not provided to zinc for a particular dependency (which indicates a performance sink)
