Bootstrap currently fails on x86_64 darwin, fixed thus.
Tested on x86_64-darwin, OK for trunk?
thanks

Since r16-603, we have a variable __limit, that is only used when
exceptions are enabled. Since we do not enable exceptions for bootstrap
of the compiler, this causes a fail (at least on Darwin) in stage 2
with .../basic_string.tcc:439:23: error: unused variable '__limit' ...
Fixed by making the variable declaration also conditional on
__cpp_exceptions.
libstdc++-v3/ChangeLog:
* include/bits/basic_string.tcc: Only declare __limit if we
are going to use it.
