Anna Zaks acdc13cb00 [analyzer] Add pointer escape type param to checkPointerEscape callback
The checkPointerEscape callback previously did not specify how a
pointer escaped. This change includes an enum which describes the
different ways a pointer may escape. This enum is passed to the
checkPointerEscape callback when a pointer escapes. If the escape
is due to a function call, the call is passed. This changes
previous behavior where the call is passed as NULL if the escape
was due to indirectly invalidating the region the pointer referenced.

A patch by Branden Archer!

Anna Zaks 0dffbd6b8e [analyzer] Convert SimpleStreamChecker to use the PointerEscape callback
The new callback greatly simplifies the checker.

Anna Zaks dc15415da4 [analyzer] Add the pointer escaped callback.
Instead of using several callbacks to identify the pointer escape event,
checkers now can register for the checkPointerEscape.

Converted the Malloc checker to use the new callback.
SimpleStreamChecker will be converted next.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Anna Zaks 302da83fc2 [analyzer] Fix a bug in REGISTER_MAP_WITH_PROGRAMSTATE
The ImmutableMap should not be the key into the GDM map as there could
be several entries with the same map type. Thanks, Jordan.

This complicates the usage of the macro a bit. When we want to retrieve
the whole map, we need to use another name. Currently, I set it to be
Name ## Ty as in "type of the map we are storing in the ProgramState".
