Add backmatch operator to pegs.
...
(backmatch [tag?]) is similar to a back reference in regular expressions
(NOT to backwards capture in a peg). It only matches a pattern if
it exactly matches the text of the last capture. It does not consume
or push any captures to the capture stack.

Fix undefined behavior bug with errors.
...
janet_vm_return_reg should only be set when janet_continue
is called. Otherwise, a panic may dump it's error message in
the wrong place, resulting in undefined behavior (often showing
the last return value or worse, segfaulting).

Fix some code style, add tuple/type function.
...
We need to be able to detect tuple type from janet code, otherwise
tuples will contain hidden state. The tuple/type function is able
to detect the flags in the tuple so the programmer can access them
if needed.

matching any possible language a computer can recognize.
