Summary: Instead of generating two i32 instructions for each load or store of a volatile i64 value (two LDRs or STRs), now emit LDRD/STRD. These improvements cover architectures implementing ARMv5TE or Thumb-2. The code generation explicitly deviates from using the register-offset variant of LDRD/STRD. In this variant, the register allocated to the register-offset cannot be reused in any of the remaining operands. Such restriction seems to be non-trivial to implement in LLVM, thus it is left as a to-do.
