is an array type not a pointer type. This requires updating some
diags that change and updating the code generator to handle the
proper form of strings.

This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)
Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)

it from several places. This merges the diagnostics, making them more
uniform and fewer in number. This also simplifies and cleans up the code.
Some highlights:
1. This removes a bunch of very-similar diagnostics.
2. This renames AssignmentCheckResult -> AssignConvertType
3. This merges PointerFromInt + IntFromPointer which were always treated the same.
4. This updates a bunch of test cases that have minor changes to the produced diagnostics.

unsigned char asso_values[] = { 34 };
int legal2() {
return asso_values[0];
}
The code that creates the new constant array type was operating on the original type.
As a result, the constant type being generated was "unsigned char [1][]" (which is wrong).
The fix is to operate on the element type - in this case, the correct type is "unsigned char [1]"
I added this case to array-init.c, which clearly didn't catch this bogosity...

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.

- Fixed many bugs, enhanced test case considerably, added a diagnostic, etc.
- Refactored CheckInitList() into CheckVariableInitList()/CheckConstantInitList().
- Added CheckInitExpr().
- Support for multi-dimensional arrays looking good.
llvm-svn: 41690
- Added Expr::isConstantExpr().
- Added type checking for InitListExpr elements.
- Added diagnostic for trying to initialize a variable sized object.

Step 1: Start instantiating InitListExpr's.
Step 2: Call newly added function Sema::CheckInitializer() from Sema::ParseDeclarator().
Step 3: Give InitListExpr's a preliminary type.
Step 4: Start emitting diagnostics for simple assignments.
Note:
As a result of step 1, the CodeGen/mandel.c test asserts "Unimplemented agg expr!", which is expected.
As a result of step 4, the test below now fails. This isn't expected and needs to be investigated (it appears type checking for C++ references is flawed in some way).
