Add fully automated mode to push-to-trunk script.

Now there are three modes to run the script:
(1) default: semi-automated
(2) manual (-m option), like in the old script
(3) forced (-f option), no user input required no editor check

Remove unnecessary overflow check in HGraphBuilder::BuildCreateAllocationMemento().

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.
