JerryScript update

[rtakacs]

The currently used JerryScript is almost the 1.0 Release (28/10/2016). I would like to update it, because there were several fixes and improvements since the last update. What's more, a new ES6 feature has been introduced, namely typed array. I would like to create a PR when #1532 will land at Jerry side.

What do you think?

[yichoi]

I would like to check the memory size first with 1.0 release and the current one.
If the memory size is not increased seriously, It might not a big problem.

@rtakacs Please note that the patch 1532 does NOT implement all features of typedarray.
It implements the constructor, set/get/define/list/delete operation, and conversions of different types.
It does NOT implement many prototype methods of typedarray, e.g. slice, sort, some, forEach,..., which will be implemented in the following patches.

Binary sizes (bytes)

@bzsolt, could you measure the binary size of jerryscript-project/jerryscript#1532?

[bzsolt]

@LaszloLango The binary size is 140208 byte on RPi2.

[LaszloLango]

@bzsolt, thank you. es2015-subset or es5.1 profile?

[jiangzidong]

According to my measurement on RPI2, jerryscript-project/jerryscript#1532 binary size for es5.1 is 140208 , and for es2015 is 144320

I am trying to figure out the gap between 140208 and 136160

[jiangzidong]

@LaszloLango ec14622's binary size is also 140208 in my RPI2... so their is no binary size regression of patch 1532.

I just run ./tools/build.py in RPI2, and use ls -l to see the binary size

[LaszloLango]

@jiangzidong, 136K is the size of the minimal main implementation. Try
./tools/build.py --jerry-cmdline-minimal=on and ls -l ./build/bin/jerry-minimal

[jiangzidong]

I see, the size of jerry-minimal after patch 1532 is 136128
