[lldb-dev] LLDB windows build and /bigobj

[Reid Kleckner via lldb-dev]

Which object file has crossed the limit? When this has happened before,
this has usually highlighted over use of templates, which is worth fixing
because it speeds up builds on other platforms as well. If MSVC 2015
instead just happens to generate say one extra section per function, then
we should probably use bigobj.
