I think $bpnum may hold this.
See the 'Set Breaks' node of the manual.
Or it can perhaps be done from Python.

A few ways.

Simplest is to use "eval".

Otherwise, Python.

Otherwise, if you have an old gdb and can't upgrade, use set logging to
write out a file with the command you want (using printf), then 'source'
the file.
