Anna Zaks fc2e153444 [analyzer] Malloc: Utter the name of the leaked variable.
Specifically, we use the last store of the leaked symbol in the leak diagnostic.
(No support for struct fields since the malloc checker doesn't track those
yet.)

+ Infrastructure to track the regions used in store evaluations.
This approach is more precise than iterating the store to
obtain the region bound to the symbol, which is used in RetainCount
checker. The region corresponds to what is uttered in the code in the
last store and we do not rely on the store implementation to support
this functionality.

Anna Zaks 0af3e06ff6 [analyzer] Rework inlining related command line options.
- Remove -analyzer-inline-call.
 - Add -analyzer-ipa=[none|inlining]
 - Add -analyzer-inlining-mode to allow experimentation for
different performance tuning methods.

Anna Zaks 265087721a [analyzer] Bound the size of the functions being inlined + provide
command line options for inlining tuning.

This adds the option for stack depth bound as well as function size
bound. 

+ minor doxygenification

Anna Zaks 43ffba2676 [analyzer] Leaks should be uniqued by the allocation point in the
closest function context. 

This prevents us from uniqueing all leaks from the same allocation
helper. radar://10932226

Anna Zaks 18de54b1a6 [analyzer] Run remove dead bindings before each call.
This ensures that we report the bugs associated with symbols going
out of scope in the correct function context.

Anna Zaks cdf24a9a5e [analyzer] We were silently stopping exploring the path after
visiting 'return;' statement!

This most likely caused us to skip a bunch of code when analyzing with
inlining.
