[lldb-dev] assert in symbolfiledwarf.cpp

[Greg Clayton]

Fixed with:

% svn commit
Sending        source/Plugins/SymbolFile/DWARF/SymbolFileDWARF.cpp
Transmitting file data .
Committed revision 167236.

It won't crash anymore, butyou will want to find out why this assert was firing off. A DWARF DW_TAG_compile_unit should have been what caused us to create the lldb_private::CompileUnit item in the first place, so for it not be able to be found a little bit later means something is very wrong.
