Implement LLVM-IR Bitcode support for the ptr_provenance optional argument of load/store instructions.

The optional argument is encoded as follows:

- when present: '1', ptr_provenance value
- when absent: '0'

If the ptr_provenance is absent, and no (future) new parameters have been added, the '0' can be omitted.
