Improve the branch and branch-trampoline mechanism to automatically
use long-jumps when function size grows large. Reduce size of emitted
trampoline pools.

The receiver needs to be checked in the same way as all other KeyedLoadICs to take non-JSObject and objects that require access checks or has interceptors into account.

The hydrogen stack check instruction is now added to each loop and the stack check handling on the back edge has been removed.

This change causes regression on small tight loops as the stack check is now at the top of the loop instead of at the bottom, and that requires one additional unconditional jump per loop iteration. However the reason for this change is to avoid worse regressions for upcoming changes to correctly support debugger break in optimized code.

Change timeType and dateType in i18n date format API into timeStyle and dateStyle to match the proposal.
I've kept old keys too, until ChromeOS user switches to time/dateStyle.

Fixed regex for matching styles in date and number format.
