Struct-path aware TBAA: uniformize scalar tag and path tag.
For struct-path aware TBAA, we used to use scalar type node as the scalar tag,
which has an incompatible format with the struct path tag. We now use the same
format: base type, access type and offset.
We also uniformize the scalar type node and the struct type node: name, a list
of pairs (offset + pointer to MDNode). For scalar type, we have a single pair.
These are to make implementaiton of aliasing rules easier.

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.

Fixed a case there the OperatingSystemPython would try to access and play with SBValue objects when the process' public run lock was taken. Prior to this fix, all attempts to run any SBValue functions would fail if run from the private state thread (like updating the thread list). Now we have two run locks, one for public (all threads except the private state thread) and one for private.
