Don't use VIXL's temp registers in LocationsBuilderARM64::HandleFieldGet.

Before this CL, when emitting a volatile field load with a
large offset, it was possible to deplete the pool of VIXL
ARM64 temporary registers (IP0, IP1) in the concurrent
collector configuration.  To avoid this, we now request a
temporary register from the register allocator instead.
