Mark top of managed stack on helper transitions
To assist with unwind from a helper function, store current SP prior
to helper call in Thread. NOTE: we may wish to push this into a
trampoline to reduce code expansion. NOTE #2: Because any helper
function which can throw will be non-leaf, it will spill lr at the saved
address - 4 (the word immediately below caller's Method*). To identify
the callsite, load the spilled lr, clear the low bit, subtract 2, and use
that address in the native <-> dalvik mapping to identify the callsite.
Also in this CL are a ralloc fix and some extra SSA logging.
