[PowerPC][NFC] Rename ADDItocL to match the 64-bit naming convention (llvm#85099)

syzaara · web-flow · commit cc761a7c3561 · 2024-03-13T11:57:07.000-04:00
In preparation of adding a similar instruction for large code model on
AIX for 32-bit, rename the exisitng ADDItocL 64-instruction to ADDItocL8
to match the naming convention of other instructions with 32-bit and
64-bit variants.
