Nick Lewycky 6b05686283 Make adding nocapture a bit stronger. FreeInst is nocapture. Also, ...

functions that don't write can't leak a pointer except through 
the return value, so a void readonly function is implicitly nocapture.

Test these, and add a test that verifies that f1 calling f2 with an 
otherwise dead pointer gets both of them marked nocapture.
