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).
Exactly what it says on the tin! There is no reason I think not to have this.
Also, I added test files for checkers that emit warning under the wrong name.

This is an attempt to avoid new false positives caused by the reverted r292800,
however the scope of the fix is significantly reduced - some variables are still
in incorrect memory spaces.
Relevant test cases added.

This reverts commit r292800.
It is causing null pointer dereference false positives when a block that
captures a static local is evaluated at the top level.
llvm-svn: 292874
When a block within a function accesses a function's static local variable,
this local is captured by reference rather than copied to the heap.
Therefore this variable's memory space is known: StaticGlobalSpaceRegion.
Used to be UnknownSpaceRegion, same as for stack locals.
Fixes a false positive in MacOSXAPIChecker.

The checker already warns for __block-storage variables being used as a
dispatch_once() predicate, however it refers to them as local which is not quite
accurate, so we fix that.

Unlike global/static variables, calloc etc. functions that allocate ObjC
objects behave differently in terms of memory barriers, and hacks that make
dispatch_once as fast as it possibly could be start failing.
