aa7198dfdd This CL simplifies var / const by ensuring the behavior is consistent in itself, and with regular JS semantics; between regular var/const and eval-ed var/const. 
Legacy const is changed so that a declaration declares a configurable, but non-writable, slot, and the initializer reconfigures it (when possible) to non-configurable non-writable. This avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects. Undefined is used instead.

457de26330 Fix arm64 deoptimization from double registers (reverts r20613). 
This reverts "ARM64: Use pair memory access in deoptimizer entry", r20613. It does not really make sense to micro-optimize the deoptimizer as it is the ultra-slow path. Moreover, the original code was easier to read (in addition to being correct).
