[SCEV] Don't always add no-wrap flags to post-inc add recs

Fixes PR27315.

The post-inc version of an add recurrence needs to "follow the same
rules" as a normal add or subtract expression.  Otherwise we miscompile
programs like

```
int main() {
  int a = 0;
  unsigned a_u = 0;
  volatile long last_value;
  do {
    a_u += 3;
    last_value = (long) ((int) a_u);
    if (will_add_overflow(a, 3)) {
      // Leave, and don't actually do the increment, so no UB.
      printf("last_value = %ld\n", last_value);
      exit(0);
    }
    a += 3;
  } while (a != 46);
  return 0;
}
```

This patch changes SCEV to put no-wrap flags on post-inc add recurrences
only when the poison from a potential overflow will go ahead to cause
undefined behavior.

To avoid regressing performance too much, I've assumed infinite loops
without side effects is undefined behavior to prove poison<->UB
equivalence in more cases.  This isn't ideal, but is not new to LLVM as
a whole, and far better than the situation I'm trying to fix.

[pdb] Finish conversion to zero copy pdb access.

This converts remaining uses of ByteStream, which was still
left in the symbol stream and type stream, to using the new
StreamInterface zero-copy classes.

RecordIterator is finally deleted, so this is the only way left
now.  Additionally, more error checking is added when iterating
the various streams.

With this, the transition to zero copy pdb access is complete.
