Log:
Now that SymbolFileDWARF supports having types in completely separate .pcm file
with "-fmodules -gmodules", each SymbolFileDWARF can reference module DWARF
info by looking in other DWARF files. Then if you have 1000 .o files that each
reference one or more .pcm files in their debug info, a simple
Module::FindTypes(...) call can end up searching the same .pcm file over and
over and over. Now all internal FindTypes methods in classes (ModuleList,
Module, SymbolFile) now take an extra argument:
llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files
Each time a SymbolFile::FindTypes() is called, it needs to check the
searched_symbol_files list to make sure it hasn't already been asked to find
the type and return immediately if it has been checked. This will stop circular
dependencies from also crashing LLDB during type queries.
This has proven to be an issue when debugging large applications on MacOSX that
use DWARF in .o files.
