Jit: Fix register usage bug - Issue 2518825 native crash running ARMv5te JIT

Change I8ca61804 added a call to dvmCanPutArrayElement for APUT_OBJECT,
but did so in a way that violated register usage restrictions.  This change
tells the register allocation system what registers we expect to remain
live across the call to dvmCanPutArrayElement.
