PR4304: Add warning for designators in strict c89 mode.

Implement support for variable length arrays in C++. VLAs are limited
...
in several important ways:
- VLAs of non-POD types are not permitted.
- VLAs cannot be used in conjunction with C++ templates.
These restrictions are intended to keep VLAs out of the parts of the
C++ type system where they cause the most trouble. Fixes PR5678 and
<rdar://problem/8013618>.

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).

Fix a minor edge case in C89 mode related to the definition of a
...
"function designator".
(This causes a minor glitch in the
diagnostics for C++ member pointers, but we weren't printing the
right diagnostic there anyway.)

Fix for PR4074: allow subscripting non-lvalue arrays in C90 mode.
...
I wasn't originally going to use this approach, but cases like
test/Sema/expr-comma.c make things difficult.

Clean up the C89/C++ warnings about C99 array features to not

emit duplicate diags (some in parser and some in sema) and to
warn about use of typequals in array sizes. This implements
PR2759.

Step #1 to fixing PR2012: c89 allows declspecs to be completely
...
missing from function definitions only. If we see a function
definiton with missing declspecs, just fudge in an int.

Fix PR1999, by emitting a hard error only if an argument declarator is completely

missing. Otherwise, it is an implicit int case, which is valid in c90 and invalid
elsewhere, but accepted as an extension.

Removed option "-parse-ast-check" from clang driver. This is now implemented
...
using "-parse-ast -verify".
Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.
Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.
