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 seventh batch of tests being updated (there are a
significant number of other tests left to be updated).
Include search paths can be relative paths. The loadSubdirectoryModuleMaps function
should account for that and respect the -working-directory parameter given to Clang.
