Dominic Chen 184c6242fa Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers 
Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

Anna Zaks 232ecfdf9c [analyzer] Include type name in Retain Count Checker diagnostics 
The more detailed diagnostic will make identifying which object the
diagnostics refer to easier.

Artem Dergachev a4e2541a70 [analyzer] Add dispatch_data_create as a special case in RetainCountChecker. 
This function receives a callback block. The analyzer suspects that this block
may be used to take care of releasing the libdispatch object returned from
the function. In fact, it doesn't - it only releases the raw data buffer.
Inform the analyzer about that. Fixes the resulting false negatives.

Devin Coughlin 8fa568d761 [analyzer] Update 'Automated' to 'Automatic' from r286694. 
ARC is 'Automatic Reference Counting' and not 'Automated Reference Counting'.

Devin Coughlin d1fe08b8a9 [analyzer] Improve misleading RetainCountChcker diagnostic under ARC 
Under automated reference counting the analyzer treats a methods -- even those
starting with  'copy' and friends -- as returning an unowned value. This is
because ownership of CoreFoundation objects must be transferred to ARC
with __bridge_transfer or CFBridgingRelease() before being returned as
ARC-managed bridged objects.

Unfortunately this could lead to a poor diagnostic inside copy methods under
ARC where the analyzer would complain about a leak of a returned CF value inside
a method "whose name does not start with 'copy'" -- even though the name did
start with 'copy'.

This commit improves the diagnostic under ARC to say inside a method "returned
from a method managed by Automated Reference Counting".
