Add resize arrays JVMTI extension
As a prototype for more general object replacement functionality add a
new JVMTI extension that allows one to change the size of arrays. This
extension is 'com.android.art.heap.change_array_size'. As far as any
JVMTI agent, JNI or Java Language code can observer this extension
atomically replaces every reference (strong and weak, global and
local, etc.) with a newly allocated array with the same contents but a
different length. Internally a whole new array will be created then
the old array will have its contents (including lock-word) copied and
all references to the old array will be replaced with the new array.
