Tracepoints add an extra wrinkle to this concept - when connecting to a 
target that is currently running a trace, tracepoint conditions can be 
uploaded from the target, and in their original source form, and so have 
to be reparsed.  So to make this work in the multi-language case, it 
seems like the tracepoint download should include the language somehow.

But then I wonder - when uploading a tracepoint, we receive both the 
computed address and the source form of that address, so in theory we 
can always deduce the correct language by working back from the 
tracepoint address.  And if that's true, then wouldn't the language of 
the condition be expected to be the same as the language of the 
location?  Are tracepoints then just a special case in which the 
condition language does not need to be recorded?
