Jon Burgess 6732e56632 Avoid assert when label is an empty string ...

Calling back() on an empty string is not allowed and triggers
an assert with recent gcc:

$ cd manual/PRESENTATION_Intro
$ ../../yosys counter.ys
...
/usr/include/c++/8/bits/basic_string.h:1136: std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::back() [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference = char&]: Assertion '!empty()' failed.

802             if (label.back() == ':' && GetSize(label) > 1)
(gdb) p label
$1 = ""
