Disabling failing tests:
- DebugInfo/BridgingHeaderPCH.swift
- DebugInfo/ClangModuleBreadcrumbs.swift
Trying to get more visibility on Linux for rebranch status.

module imports. This is useful when building redistributable static
archives, since any pointers into the CLang module cache won't be
portable.
When using this option the Clang type fallback path in LLDB will be
less useful since DWARF type information from those modules will not
be available unless another object file compiled without the option
imported the same modules.
