This reverts commit a437b4b469.
Reason for revert: Build on Windows appears broken.
Original change's description:
> Re-land "[vm/kernel/precomp] Remove procedures from entry points files."
>
> The original revision is in Patchset 1.
>
> Due to idiosyncrasies of the legacy VM parser, we need to put the @pragma definition
> on both the original and patched definition. Hopefully we can remove these extra definitions
> once Dart 1 AOT is fully obsolete.
