reduce the size of IrInstruction by 8 bytes on 64 bit targets

Browse Source 
This brings the std lib tests down from 3.51 GiB memory usage
to 3.41 GiB, by making two fields that were 64 bits 32 bits.
This is a small thing; the bigger wins will come from the strategy
outlined in the previous commit.
