CFI: Append debug location to CFI blocks

Currently we're not appending debug locations to the inserted CFI blocks. This shows up in #132615 and #100783. This change fixes that by passing down the debug location to the CFI type-test generation and appending it to the blocks.

Credits also belong to `@jakos-sec` who worked with me on this.
