Fix: <rdar://problem/6850275> CF objects returned from methods with "new" or "copy" in their name should be treated as owned

For methods that follow the "fundamental rule" and return Core
Foundation objects, treat those objects as owned by the caller.

Convert ArgEffects from an std::vector to an ImmutableMap.  This will make it much easier to clean up the summary generation logic with annotations.

reason for adding these is to error out in CodeGen when trying to generate
them instead of silently emitting a call to a non-existent function.

(Note that it is not valid to lower these to setjmp/longjmp; in addition 
to that lowering being different from the intent, setjmp and longjmp 
require a larger buffer.)

fix-it hint is much worse than no fix-it hint. (Fixes PR4084).

When we need to truncate a source line to fix in the terminal, make
sure to take the width of the fix-it information into account, too.

of returning a list of pointers to Values that are deleted. This was
unsafe, because the pointers in the list are, by nature of what
RecursivelyDeleteDeadInstructions does, always dangling. Replace this
with a simple callback mechanism. This may eventually be removed if
all clients can reasonably be expected to use CallbackVH.

Use this to factor out the dead-phi-cycle-elimination code from LSR
utility function, and generalize it to use the
RecursivelyDeleteTriviallyDeadInstructions utility function.

This makes LSR more aggressive about eliminating dead PHI cycles;
adjust tests to either be less trivial or to simply expect fewer
instructions.
