[RISCV] Add C intrinsics for scalar bitmanip and crypto

[craig.topper]

Summary

This adds riscv_bitmanip and riscv_crypto.h

This is based on the proposed spec here https://github.com/riscv-non-isa/riscv-c-api-doc/pull/44

Tests that previously used builtins directly now use the intrinsics.

[craig.topper]

git add the header

[craig.topper]

Fix file description

[craig.topper]

Fix name of zip/unzip builtin

[wangpc]

Can we run mem2reg pass in RUNs just like RVV tests (maybe another cleanup patch)? I think there are a lot of noises in CHECKS.

[craig.topper]

Rebase after using mem2reg.
Fix a couple copy/paste mistakes that were much easier to spot with mem2reg.

[craig.topper]

Add riscv_bitmanip.h to cover all of Zbb and Zbkb

[VincentWu]

LGTM, But waiting for other reviewers.

[wangpc]

LGTM if the proposal is merged.

[craig.topper]
