Mythri 807d0abe4f Change runtime_profiler to use bytecode array length
Runtime profiler uses bytecode array size for the tiering up decisions.
Bytecode array size includes the header size as well. Inlining
heuristics use bytecode array length instead. Bytecode array length
is just the size of bytecode not inlcuding any headers. This change
is to keep both of them in sync to avoid confusion. Also, the header
contains several pointers and hence the size changes depending on the
size of kPointerSize.
