By adding a default config.excludes pattern we can avoid individual
suppressions in subdirectories.
This matches LLVM's lit.cfg which also excludes a few other common non-test
filenames for consistency.

This patch does a few different things.
This patch improves unused var diags for const vars: we no longer
unconditionally suppress diagnostics for const vars, instead only suppressing
the diagnostic when the declaration appears to be useful.
This patch also makes us more consistently use whether a variable/function
is declared in the main file to suppress diagnostics where appropriate.
Fixes <rdar://problem/14907887>.

fact be defined and used in another TU.
Reshuffle some test cases because we suppress -Wunused-variable after we've
emitted an error.
This fixes PR15558.

The motivation here is a "clever" implementation of strncmp(), which peels the first few comparisons via chained conditional expressions which ensure that the input arrays are known at compile time to be sufficiently large.

headers, where malloc (and many other libc functions) are declared
with empty throw specifications, e.g.,
extern void *malloc (__SIZE_TYPE__ __size) throw () __attribute__
((__malloc__)) ;
The C++ standard doesn't seem to allow this, and redeclaring malloc as
the standard permits (as follows) resulted in Clang (rightfully!)
complaining about mis-matched exception specifications.
void *malloc(size_t size);
We work around this by silently propagating an empty throw
specification "throw()" from a function with C linkage declared in a
system header to a redeclaration that has no throw specifier.
Ick.
