Simplified initializer semantic analysis by adding the following 2 methods:

- ArrayType::getBaseType(), and 
- ConstantArrayType::getMaximumElements().

Wanted to do this cleanup before adding structure support, which will add more complexity.

Always check the type of node. This prevents situations such as selecting 32-bit rotate target instruction for a 64-bit node when 64-bit pattern is missing.

Update GEP constructors to use an iterator interface to fix
GLIBCXX_DEBUG issues.

Make sure initializer type promotions get propagated.

This fixes a recent regression with Codegen/mandel.c.

More fun with initializers! 

- 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.

Finish getting "array-init.c" to work properly.

Array scalar initialization is now is reasonable shape.

Next step, structure and array of structure initializers.

Emit proper "secrel" directive, where possible. This fixes invalid asm syntax of debug info on mingw32. Also, cleanup 
some stuff.

More progress on array initializers.

- Added Expr::isConstantExpr().
- Added type checking for InitListExpr elements.
- Added diagnostic for trying to initialize a variable sized object.

llvm-svn: 41674

Added 2 errors and one warning, updated test case.

Start implementing semantic analysis for C initializers.

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).

Finish converting SwitchStmt AST to source ranges.
Move DumpSourceRange() to DumpStmt().

Now -parse-ast-dump will display source range info for all stmts/exprs.

One day we should implement the source range protocol for Decls.
