  -----------
  [RISCV] Add a non-template version of SelectAddrRegZextRegScale and move code there. NFC

The template versions now call the non-template version. This
avoids duplicating the code for each template.

  [libclc] Expose `prepare_builtins_*` variables in top-level CMakeLists (#149657)

Fix `libclc/utils/CMakeLists.txt` to expose `prepare_builtins_*`
variables in parent scope. This was a regression introduced in #148815
where the code was moved into subdirectory, and the variables would no
longer be accessible to calls in top-level CMakeLists, resulting in
attempting to build targets with empty command:

```

  MC: Optimize emitInstruction and simplify fragment-in-BSS check

Move the FT_Relaxable-in-BSS check from frequently-called
MCObjectStreamer::emitInstruction to MCAssembler::writeSectionData,
along with existing checks for other fragment types. For the uncommon
diagnostics, losing the location information is acceptable.
