ae088e52f3 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.

19a63fc6fa Add the ability to pass an EvaluateExpressionOptions when you make a UserExpression. This
isn't used in this commit but will be in a future commit.

998c8a1c1c Create an expression parser for Go.
The Go interpreter doesn't JIT or use LLVM, so this also
moves all the JIT related code from UserExpression to a new class LLVMUserExpression.
