each other in the AST, giving the ugly diagnostics in L8.

statements don't end up in the LabelMap so we don't have a quick way
to filter them.  We could add state to Sema (a "has vla" and "has 
jump" bit) to try to filter this out, but that would be sort of gross
and I'm not convinced it is the best way.  Thoughts welcome.

Turns out that doing this by hand is easier than using autoreconf:-).

Make CodeGenFunction::EmitCallArgs a template function that takes a generic "Type Info" parameter. The type info parameter knows how to iterate over its arguments.

type as the vector element type: allow them to be of
a wider integer type than the element type all the way
through the system, and not just as far as LegalizeDAG.
This should be safe because it used to be this way
(the old type legalizer would produce such nodes), so
backends should be able to handle it.  In fact only
targets which have legal vector types with an illegal
promoted element type will ever see this (eg: <4 x i16>
on ppc).  This fixes a regression with the new type
legalizer (vec_splat.ll).  Also, treat SCALAR_TO_VECTOR
the same as BUILD_VECTOR.  After all, it is just a
special case of BUILD_VECTOR.

want the current block label.  No functionality change.

specific bad case instead of on the switch.  Putting it on the
switch means you don't know what case is the problem. For 
example:

scope-check.c:54:3: error: illegal switch case into protected scope
  case 2:
  ^
scope-check.c:53:9: note: jump bypasses initialization of variable length array
    int a[x];
        ^

completely illegal, don't even bother using numericliteralparser for them.

Configure was not actually regenerated, but the change last time only touched
this one line, so I'm being lazy and cheating by fixing it manually.

produce better diagnostics, and be more correct in ObjC cases (fixing
rdar://6803963).

An example is that we now diagnose:

int test1(int x) {
  goto L;
  int a[x];
  int b[x];
  L:
  return sizeof a;
}

with:

scope-check.c:15:3: error: illegal goto into protected scope
  goto L;
  ^
scope-check.c:17:7: note: scope created by variable length array
  int b[x];
      ^
scope-check.c:16:7: note: scope created by variable length array
  int a[x];
      ^

instead of just saying "invalid jump".  An ObjC example is:

void test1() {
  goto L;
  @try {
L: ;
  } @finally {
  }
}

t.m:6:3: error: illegal goto into protected scope
  goto L;
  ^
t.m:7:3: note: scope created by @try block
  @try {
  ^

There are a whole ton of fixme's for stuff to do, but I believe that this
is a monotonic improvement over what we had.
