Use functions with prototypes when appropriate; NFC

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 first batch of tests being updated (there are a significant
number of other tests left to be updated).

[PowerPC] Disable vector types when not supported by subtarget features

Update clang to treat vector unsigned long long and friends as invalid
for AltiVec without VSX.

[Clang][Sema]Choose a better candidate in overload function call if there is a compatible vector conversion instead of ambiguous call error

There are 2 function variations with vector type parameter. When we call them with argument of different vector type we would prefer to 
choose the variation with implicit argument conversion of compatible vector type instead of incompatible vector type. For example,

typedef float __v4sf __attribute__((__vector_size__(16)));
void f(vector float);
void f(vector signed int);

int main {
   __v4sf a;
   f(a);
}

Here, we'd like to choose f(vector float) but not report an ambiguous call error.
