1ea584377e 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 ninth batch of tests being updated (there are a
significant number of other tests left to be updated).

bd42582541 [analyzer] Ignore calculated indices of <= 0 in VLASizeChecker 
Summary:
See https://bugs.llvm.org/show_bug.cgi?id=46128. The checker does not
yet comprehend constraints involving multiple symbols, so it's possible
to calculate a VLA size that's negative or 0. A LIT is added to catch
regressions, and this change simply bails if a VLA size of 0 or less is
calculated.

cb1eeb42c0 [Analyzer][VLASizeChecker] Check VLA size in typedef and sizeof. 
Summary:
The check of VLA size was done previously for variable declarations
(of VLA type) only. Now it is done for typedef (and type-alias)
and sizeof expressions with VLA too.
