Comment:

 OK, I see how the loopification patch works. Previously we had:

 {{{
 c4AC:
     call "ccall" arg hints:  [PtrHint,
                               PtrHint]  result hints:  []
 enterFunCCS(BaseReg, I64[R1 - 1 + 8]);
 }}}

 Now we have:

 {{{
 c4AC:
     call "ccall" arg hints:  [PtrHint,
                               PtrHint]  result hints:  []
 enterFunCCS(BaseReg, I64[_s2UW::P64 - 1 + 8]);
 }}}

 The `_s2UW::P64` is declared anyway so no extra work required :-)
