JS Built-ins functions should be able to assert
https://bugs.webkit.org/show_bug.cgi?id=150333
Reviewed by Yusuke Suzuki.
Source/JavaScriptCore:
Introduced @assert to enable asserting in JS built-ins.
Adding a new bytecode 'assert' to implement it.
In debug builds, @assert generates 'assert' bytecodes.
In release builds, no byte code is produced for @assert.
In case assert is false, the JS built-in and the line number are dumped.
