93cd816c07 Make TemplateLiteral hashing algorithm more memory efficient 
Previously, a separate string to be hashed (in order to help determine the need to
use a cached Template Call Site) was built up by joining UTF8 spans within a template.

Now, the hash key is generated from the original spans, removing the need to allocate a new
buffer and copy bytes into it.

a03943880c MIPS: harmony-scoping: make assignment to 'const' a late error. 
Port 6ac4de87a8

Original commit message:
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

9da4998204 Abort optimization in corner case. 
The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.

fd13969ef0 Disable ParserSync test for now, it takes waaaaay too long. 
Running this in x64.release mode on a powerful HP620 takes 4 seconds,
this is at least 2 orders of magnitude too slow and leads to tons of
false positives on our build bots due to timeouts. As it is, the
cost-benefit ratio is far too low.

The whole approach needs to be changed: Instead of trying to exhaust
some search space in unit tests, this should be turned into a fuzzing
test where only a small but random number of things are tested. The
exhaustive approach can be done separately, but definitely not in the
unit tests.
