/**
 * Issue #1143: Compiler-version axis of a toolchain requirement.
 *
 * No requirement currently carries a floor -- the last one was removed with the
 * unreachable __builtin_*_overflow calls. This type exists so that adding a
 * construct with a version floor is a data change rather than a redesign, and
 * so RequirementGuardGenerator can emit a guard for it automatically.
