tr/// functions: add some basic code comments

For the various C functions which implement the compile-time and
run-time aspects of OP_TRANS, add some basic code comments at the top of
each function explaining what its purpose is.

Also add lots of code comments to the body of S_pmtrans() (which compiles
a tr///).

Also comment what the OPpTRANS_ private flag bits mean.

No functional changes.
