simple test that actually does VLA codegen.
Note that despite the fact that the alloca isn't in the entry block, it
should dominate all uses; this is guaranteed by the restrictions on goto
into VLA scope in C99.

write update bit-field value if caller requires it.

CodeGenFunction.cpp. Change VisitConditionalOperator to use
constant fold instead of codegen'ing a constant conditional.
Change ForStmt to use EmitBranchOnBoolExpr, this shrinks
expr.c very slightly to 40239 lines.

- EmitStmt is no longer required to finish with a current insertion
point defined (i.e. it does not need to make dummy
blocks). Instead, it can clear the insertion point in the builder
which indicates that the current insertion point is unreachable.
- CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint
which respectively test if there is an insert point and ensure an
insertion point exists (by making a dummy block).
- Clearly mark functions in CodeGenFunction which can be called with
no insertion point defined. Currently this is a limited set, and
EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR.
Remove EmitDummyBlock, which is no longer needed. Clients who haven't
already cleared the insertion point (typically via EmitBranch) can do
so by hand.
Remove isDummyBlock, which has effectively been renamed to
HaveInsertPoint.
The main thrust of this change is that we no longer have create dummy
blocks just to destroy them a short time later in EmitBlock in the
common case that there is no unreachable code following something like
a goto.
Additionally, this means that we are not using the hokey condition in
isDummyBlock that a block without a name is a dummy block. Guess how
well that works when we never emit block names!

the size of the -O0 output on some cases. For example, on expr.c from
176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed

- Important for allowing Obj-C void * to id<X> casts and so on.
- Not sure about this fix however, perhaps Type should understand
that id is effectively a pointer type.

Implement Obj-C lvalue message sends (aggregate returns).
Update several places to emit more precise ErrorUnsupported warnings
for currently unimplemented Obj-C features (main missing chunks are
property references, Obj-C exception handling, and the for ... in
syntax).

- Returns an RValue.
- Reduced to only taking the CodeGenFunction, Expr, and Receiver.
- Becomes responsible for emitting the arguments.
Add CodeGenFunction::EmitCallExprExt
- Takes optional extra arguments to insert at the head of the call.
- This allows the Obj-C runtimes to call into this and isolates the
argument and call instruction generation code to one place. Upshot
is that we now pass structures (more) correctly.
Also, fix one aspect of generating methods which take structure
arguments (for NeXT). This probably needs to be merged with the
SetFunctionAttributes code in CodeGenModule.cpp

- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr -
ptr) so that implementation matches that of other operators.
- Modify EmitCompoundAssign to compute and perform the appropriate
casts of left, right, and result types for the assorted pointer
arithmetic cases.
- Fix EmitSub (ptr - int) case to negate the rhs *after*
extension. This is critical when the rhs is unsigned (and needs
extension).
- This fixes cfrac.
