when compiling in a GNU mode (e.g. gnu99) treat VLAs with a size that can be folded to a constant
...
as constant size arrays. This has slightly different semantics in some insane cases, but allows
us to accept some constructs that GCC does. Continue to be pedantic in -std=c99 and other
modes. This addressed rdar://8733881 - error "variable-sized object may not be initialized"; g++ accepts same code

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

Extend the implicit declaration and checking against out-of-scope
...
external declarations to also support external variable
declarations. Unified the code for these two cases into two new
subroutines.
Note that we fail to diagnose cases like the one Neil pointed
out, where a visible non-external declaration hides an external
declaration by the same name. That will require some reshuffling of
name lookup.

Fix the location we emit the "not a constant" error for this:

previously we'd emit it on the typedef, which made not sense at all.
