Re-commit: r366610 and r366612: Expand pseudo-components before embedding in llvm-config
There were two main problems:
* The 'nativecodegen' pseudo-component was unconditionally adding
${native_tgt}CodeGen even though it conditionally added ${native_tgt}Info and
${native_tgt}Desc. This has been fixed by making ${native_tgt}CodeGen
conditional too
* The 'all' pseudo-component was causing library names like LLVMLLVMDemangle as
the expansion was to a library name and not a component. There doesn't seem to
be a list of available components anywhere so this has been fixed by moving the
expansion of 'all' back where it was before. This manifested in different ways
on different builders but it was the same root cause
