A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the eighth batch of tests being updated (there are a
significant number of other tests left to be updated).
Statement memoization was removed in r348822 because it was noticed to cause
memory corruption. This was happening because a reference to an object
in a DenseMap was used after being invalidated by inserting a new key
into the map.
This test case crashes reliably under ASan (i.e., when Clang is built with
-DLLVM_USE_SANITIZER="Address") on at least some machines before r348822
and doesn't crash after it.

Do not warn when the other message-send-expression is correctly wrapped
in a different autorelease pool.

A checker for detecting leaks resulting from allocating temporary
autoreleasing objects before starting the main run loop.
Checks for two antipatterns:
1. ObjCMessageExpr followed by [[NARunLoop mainRunLoop] run] in the same
autorelease pool.
2. ObjCMessageExpr followed by [[NARunLoop mainRunLoop] run] in no
autorelease pool.
Happens-before relationship is modeled purely syntactically.
