  Log Message:
  -----------
  [CIR] Reject language address spaces in DirectToLLVM pointer conversion

Reject unlowered language address spaces in pointer types when bypassing TargetLowering. Guard pointer-producing lowerings, including generated patterns, so failed conversions report legalization failures instead of silently selecting address space zero or constructing invalid LLVM operations.
