This patch fixes the issue that we were using the C stack as a measure of depth of ValueObject hierarchies, in the sense that we were assuming that recursive ValueObject operations would never be deeper than the stack allows.
This assumption is easy to prove wrong, however.
For instance, after ~10k runs through this loop:
struct node
{
int value;
node* child;
node (int x)
{
value = x;
child = nullptr;
}
};

int main ()
{
node root(1);
node* ptr = &root;
int j = 2;
while (1)
{
ptr->child = new node(j++);
ptr = ptr->child;
}
return 0;
}

the deepmost child object will be deeper than the stack on most architectures, and we would be unable to display it

This checkin fixes the issue by introducing a notion of root of ValueObject hierarchies.
In a couple cases, we have to use an iterative algorithm instead of going to the root because we want to allow deeper customizations (e.g. formats, dynamic values).
While the patch passes our test suite without regressions, it is a good idea to keep eyes open for any unexpected behavior (recursion can be subtle..)
Also, I am hesitant to introduce a test case since failing at this will not just be marked as an "F", but most definitely crash LLDB.

Fix for wrong instcombine on vector insert/extract

instructions into single shuffle instructions, there is one specific
case where the Instruction Combiner wrongly updates the resulting
Mask of shuffle indexes.

The problem is in function CollectShuffleElments.

If we have a sequence of insert/extract element instructions
like the one below:

  %tmp1 = extractelement <4 x float> %LHS, i32 0

Where:
  . %RHS will have a mask of [4,5,6,7]
  . %LHS will have a mask of [0,1,2,3]

The Mask of shuffle indexes is wrongly computed to [4,1,6,7]
instead of [4,0,6,7].
When analyzing %tmp2 in order to compute the Mask for the
resulting shuffle instruction, the algorithm forgets to update
the mask index at position 1 with the index associated to the
element extracted from %LHS by instruction %tmp1.
