Some problems with llvm debugging.

Test log from lldb 10.0.0 - not recognized main function name 
(but other is found), not steps next line (expect goto finally 
expression) after throw exception.

Compile>ldc2 -gdwarf -gc -m64 except.d

Used MSVC Build tools 2019 (as -v option tells), but lld-link.
