0ca02ee48d Make sure builtin functions don't rely on __proto__. 
This makes sure that none of the builtin functions rely on the __proto__
accessor which can now be monkey-patched by applications. Instead use a
separate %SetPrototype() intrinsic or object literals to do the job.

1336b913d0 Make built-ins strict mode conforming, and support a --use-strict flag. 
* Turned all uses of 'const' into 'var'.
* Turned all uses of local 'function' into 'var'.
* Added a couple of missing toplevel 'var' declarations.

One consequence is that the properties on the builtin object  are no longer
non-writable, and I had to adapt one test. Is that a problem?

Unfortunately, we cannot actually switch the library scripts to strict mode
by default, because that makes observable things like poisoned .caller properties
for library functions.

Also removed dead flag code in Compiler::Compile.
