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 tenth batch of tests being updated (there are a
significant number of other tests left to be updated).
`__block` variables used to be always stored on the head instead of stack.
D51564 allowed `__block` variables to the stored on the stack like normal
variablesif they not captured by any escaping block, but the debug-info
generation code wasn't made aware of it so we still unconditionally emit DWARF
expressions pointing to the heap.
This patch makes CGDebugInfo use the `EscapingByref` introduced in D51564 that
tracks whether the `__block` variable is actually on the heap. If it's stored on
the stack instead we just use the debug info we would generate for normal
variables instead.

There doesn't seem to be a direct test of this, and I'm planning to make
future changes which will affect it.
I'm not particularly familiar with the blocks extension, so suggestions
for better tests are welcome.
