tip to Weiliang Lin for discovering the bug.

If OSR happens before regular recompilation, the unoptimized function code
on the stack may not have deoptimization support.  In that case, graph
creation compiles the unoptimized code again to include support.  That
code is then installed as shared code.  When we patch code for OSR, the
function code on the stack and not the shared code is what we want.

With this fix codegen looks like:

mov ecx,[eax+0xf]  ;;; <@52,#38> load-named-field
add ecx,0x2  ;;; <@54,#40> add-i
mov [eax+0xf],ecx  ;;; <@56,#41> store-named-field

without it there is an overflow check and jump to deopt.

x64 code looks similar, except there is an (annoying) smi-untag then int32-to-smi around the add operation.
