[PATCH] D13914: Tolerate negative offset when matching sample profile.

Update the discriminator assignment algorithm.

- If a scope has already been assigned a discriminator, do not reassign a nested discriminator for it.
- If the file and line both match, even if the column does not match, we should assign a new discriminator for the stmt.
