This is important because each call produces a new Array, which

The debugger script implementation had its own way to write
uint32_t values to a string as hex values. This removes the
custom code and uses a shared implementation in String16Builder
instead.
The observable effect is that script hashes are now lower-case
and the character sequence is reversed for each 8-character
pair.

Previously GetSharedFunctionInfoForStreamedScript didn't either check the
compilation cache or put the result of compilation into the compilation
cache. This would mean future compiles would need to re-parse / compile
the same script even if the isolate had already seen it. This CL
fixes this.
Also refactors the compilation pipelines to ensure we call debug->OnAfterCompile()
for all script compiles even when loading from a cache.

We already cleanup these scripts on frontend side. It is crucial to
cleanup them on backend side as well, since some web applications use
following logic: get some data from network, add this data to buffer,
try to parse buffer using JSON.parse. On each unsuccessfull JSON.parse
we get another scriptFailedToParse event.
Frontend logic of discarding scripts: https://goo.gl/FDtaWK
Some idea of smarter logic here: track what script ids are reported
using protocol and cleanup only script ids which reported not only as
part of scriptFailedToParse event.
