runtime/vm/intrinsifier_ia32.cc:613: __ movl(EDX, Address(ESP, + 1 *
kWordSize));  // Value.
You cannot use EDX if you can fall through to the slow case (see comment at the
head of file).

runtime/vm/intrinsifier_x64.cc:439: __ movq(RBX, Address(RSP, + 2 * kWordSize));
 // Index.
You cannot use RBX if there is a slow path. This is also valid for code above.
(see comment at head of file: RBX, R10 can be used only if there is no
fall-through)
