Nick Desaulniers 728a45181d [libcxxabi] copy back std::string_view patches from LLVM
I made a series of changes to LLVM's demangle in:
- D148348
- D148353
- D148363
- D148375
and so did Fangrui in 3ece37b3fa2c and Ashay in D149061.

I didn't notice the banner about there being two copies of this in tree
and was modifying the downstream versions. Copy these changes back to
the upstream version. Oops!
