Add opcodes for volatile field accesses
This adds instructions for {i,s}{get,put}{,-object}-volatile, for a
total of eight new instructions.
On SMP systems, these instructions will be substituted in for existing
field access instructions, either by dexopt or during just-in-time
verification. Unlike the wide-volatile instructions, these will not be
used at all when the VM is not built for SMP.
(Ideally we'd omit the volatile instruction implementations entirely on
non-SMP builds, but that requires a little work in gen-mterp.py.)
The change defines and implements the opcodes and support methods, but
does not cause them to be used.
Also, changed dvmQuasiAtomicRead64's argument to be const.
