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 ninth batch of tests being updated (there are a
significant number of other tests left to be updated).
There are still plenty of tests that specify x86 as a triple but most shouldn't be doing anything very target specific - we can move any ones that I have missed on a case by case basis.
