[ConstantTime] Apply review fixes for llvm.ct.select core - Verifier: reject aggregate types instead of crashing ISel; add test. - Fix scalable-vector expansion crash when the element type is not a legal scalar; add RVV test. - LangRef: document poison/undef, noundef, permitted folds, and FMF behavior; rewrite Syntax/Overview. - Deduplicate CT_SELECT type-legalizer handlers into the SELECT paths. - Misc: FP int-twin assert, dead null check, in-place memory blend, flag-free PromoteNode, GlobalISel fallback test, comment cleanups.
