Introduce FLAG_vector_ics.

When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
will allocate a type vector slot to store feedback information. Full codegen
will emit a load of the slot into a register if the flag is on.

Support is incomplete, right now the IC doesn't know how to use the feedback
slot.

Fix automatic version update.

This fixes two things:
1. Guarantee that versions are bumped up also when presubmit errors exists. Those errors originate from other CLs and should not stop the automatic versioning.
2. Calculate the last bleeding edge version when pushing to trunk based on remote branch svn/bleeding_edge and not on local branch master. The master branch is not kept up-to-date by the script.

Use 0 instead of undefined for uninitialized stub key.
