RFR: 8335662: [AArch64] C1: guarantee(val < (1ULL << nbits)) failed: Field too big for insn [v2]

> Crash occurs in C1 during OSR when copying locks from interpreter frame to compiled frame. All loads used immediate offset regardless of offset size causing crash when it is over the max size for the instruction (32760). Fix is to check the size before preforming the load and storing the offset in a register if needed.
> 
> I believe the risk is low because there will be no change to the instruction if the immediate offset fits in the load instruction. The instruction is only updated when the `offset_ok_for_immed` check fails which would cause the crash anyways
> 
> Confirmed that added test fails before patch and passes after
