Support deoptimization only to set vreg
This CL removes the old API that was used to update vreg. We now rely
exclusively on deoptimization to change the value of a vreg (mainly
from the debugger). This allows to have only one mechanism working
with both Quick and Optimizing compilers. It also remove run-test
455-set-vreg which was the only user of the old API.
This CL also renames StackVisitor::SetVReg[Pair]FromDebugger to
StackVisitor::SetVReg[Pair] to reflect that change.
