most probably, but what does it mean if clang have multiple layers,
frontend, LLVM backend, etc. etc. for normal user who just needs C
It doesn't matter how it do this but what are the results.

You didn't wrote anything new here.

It doesn't really care how clang is written but how it works. And it was
political decision because compiler itself, on GPLv3 licence, does not
block anyhow distributing it's output - binaries.
C++ libraries can be limiting, but... wasn't replaced.
If it would be truly about removing GPLv3 code that hurts, replacing
libstdc++ would be first thing to do.
For now we have removed GPL code that doesn't hurt
