No, there is a misunderstanding.  jit_bltr_i means

Branch
if Less Than Register
operand size = Integer

In general all operations are
: jit_XXXr_TT register <- register OP register, signed type TT
: jit_XXXi_TT register <- register OP immediate, signed type TT
: jit_XXXr_uTT register <- register OP register, unsigned type TT
: jit_XXXi_uTT register <- register OP immediate, unsigned type TT

Your other patches are fine and I'll merge them soon.
