Eli Friedman 3fa64df543 Refactor and fix checking for initialization of flexible array members. The old version had the checks scattered across the code, missed some checks, and had a couple nasty bugs in existing checks.
Fixes PR10648 and another similar accepts-invalid bug.

Douglas Gregor 1f81ced14c Allow list-initialization of a local variable of class type with a
flexible array member, so long as the flexibility array member is
either not initialized or is initialized with an empty initializer
list. Fixes <rdar://problem/8540437>.

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).

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Douglas Gregor 07d8e3a500 Allow flexible array initializers that are not surrounded by
braces. We now build the appropriate fully-structured initializer list
for such things. Per PR3618, verified that we're getting the right
code generation.

Douglas Gregor 1cba5fe1d1 Downgrade the "excess elements in initializer" errors to warnings *in
C*. They're required errors in C++.

Douglas Gregor 09cfcff492 GNU allows structs with flexible array members to be placed inside
arrays and other structs/unions as an extension. Downgrade our error
to a warning. Fixes PR3540.

Sebastian Redl 2175b6a767 Make one expected-diag directive match exactly one actual diagnostic.
This uncovers some bugs, so several test cases now fail.

Douglas Gregor fc4f8a1834 Implement semantic analysis for the GNU flexible array initialization
extension. The interaction with designated initializers is a
bit... interesting... but we follow GNU's lead and don't permit too
much crazy code in this area.

Also, make the "excess initializers" error message a bit more
informative.
