The stack manipulation was expensive. Two virtual registers are better. BUG= Review URL: https://codereview.chromium.org/1376933006 Cr-Commit-Position: refs/heads/master@{#31204}

(reason for revert/reland: patch incorrectly left --vector-stores flag on, helpfully revealing some gcstress issues to look at, but they don't need to block this CL). Some pretty hacky code was used to carry out the tail-call handler dispatch on ia32 vector stores due to a lack of free registers. It really tanks performance. A better approach is to use a virtual register on the isolate.

The last changes for vector store functionality, they are in 3 areas: 1) The new vector [keyed] store code stubs - implementation. 2) IC and handler compiler adjustments 3) Odds and ends. A change in ast.cc, a test update, a small Oracle fix.

the megamorphic load case in hydrogen. A simple approach is to wrap the probe activity in a hydrogen instruction. The instruction is novel in that it always tail-calls away.
