arch: Provide traceback when parsing ISA code

There is no line information When the ISA code is executed inside the
isa_parser environment and an error is encountered. The build stops and
reports the line of the let block containing the error.
This patch is enhacing the error reporting by printing the traceback of
the faulting ISA code.
