'i8l' LIR transformation replaces operations with 64 bits integer values with a set of operations supported by IA-32 ISA.
The I8PseudoInstruction is normally generated by hir2lir transformation for every operation with 64-bit integer values using 64-bit operands.
This transformation replaces these instruction with platform instructions available on IA32 platform, replacing 64-bit operands with pairs of 32-bit ones if needed.
