Tamas Berghammer 2ff8870b6f Re-commit "Make dwarf parsing multi-threaded" ...

Re-commit the change after fixing a lot of race condition in LLDB
exposed by this change

Loading the debug info from a large application is the slowest task
LLDB do. This CL makes most of the dwarf parsing code multi-threaded.

As a result the speed of "attach; backtrace; exit;" when the inferior
is an LLDB with full debug info increased by a factor of 2.
