Chris Lattner f35de48c90 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

Daniel Dunbar 8fbe78f6fc 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).

Chris Lattner 0f94c5a741 Fix PR4092 by improving error recovery in two ways:
1. In a struct field redefinition, don't mark the struct erroneous.  The
   field is erroneous, but the struct is otherwise well formed.
2. Don't emit diagnostics about functions that are known to be broken already.

Either fix is sufficient to silence the second diagnostic in the example,
but the combination is better :)

Tests and drivers updated, still need to shuffle dirs.

Douglas Gregor 3e06dbf48c Downgrade complaints about the use of variable-sized types within a
struct to an extension warning to match the behavior of GNU C, which
addresses the Sema part of PR3671.

Eli Friedman 2194bb78ec Sanity fix for PR3642: if we're treating a diagnostic as an error, it's
required to actually be an error for correctness.  The attached testcase 
now gives an error instead of mysteriously crashing.

Now, it's possible we actually want to support the given usage, but I 
haven't looked at the relevant code closely.

Douglas Gregor 8761da5f68 Simplify the way in which we inject the names of tag definitions and
elaborated-type-specifier declarations into outer scopes while
retaining their proper lexical scope. This way is simpler and more
consistent with the way DeclContexts work, and also fixes
