Aaron Ballman 22db4824b9 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 third batch of tests being updated (there are a significant
number of other tests left to be updated).

Fangrui Song c6a384df1f [Sema] Special case -Werror-implicit-function-declaration and reject other -Werror-
This is the only -Werror- form warning option GCC supports (gcc/c-family/c.opt).
Fortunately no other form is used anywhere.

r278501 inadvertently introduced a bug in which it disallowed shifting
scalar operands by vector operands when not compiling for OpenCL. This
commit fixes it.
