[JSC] Should not emit get_by_id for indexed property access
​https://bugs.webkit.org/show_bug.cgi?id=151354

Reviewed by Darin Adler.

Before this patch, a["1"] is converted to a.1 get_by_id operation in the bytecode compiler.
get_by_id emits IC. IC rely on the fact that Structure transition occur when adding / removing object's properties.
However, it's not true for indexed element properties. They are stored in the element storage and Structure transition does not occur.

For example, in the following case,

function getOne(a) { return a1; }

for (var i = 0; i < 36; ++i)

getOne({2: true});

if (!getOne({1: true}))

throw new Error("OUT");

In this case, a['1'] creates get_by_id. getOne({2: true}) calls makes getOne's get_by_id to create IC says that,
"when comming this structure chain, there is no property in "1", so we should return undefined".

After that, we call getOne({1: true}). But in this case, {2: true} and {1: true} have the same structure chain,
because indexed property addition does not occur structure transition.
So previous IC fast path is used and return undefined. But the correct answer is returning true.

This patch fixes the above issue. When there is string bracket access, we only emits get_by_id if the given string is not an index.
There are bugs in get_by_id, put_by_id, put_by_id (direct). But only get_by_id poses user observable issue.
Because in the put_by_id case, the generic path just says "this put is uncacheable".

CachedScript could have a copy-free path for all-ASCII scripts.
<​https://webkit.org/b/152203>

Source/JavaScriptCore:

Reviewed by Antti Koivisto.

Make SourceProvider vend a StringView instead of a String.
This relaxes the promises that providers have to make about string lifetimes.

This means that on the WebCore side, CachedScript is free to cache a String
internally, while only ever exposing it as a temporary StringView.

A few extra copies (CPU, not memory) are introduced, none of them on hot paths.

Many (if not most) of script resources on the web contain nothing but ASCII characters.
Such resources, when streamed through a text decoder, will yield the exact same byte

resource data if an asynchronous caching notification comes in.

Clean up absolute positioned map properly.

Reviewed by Simon Fraser.

We insert positioned renderers into a static map (RenderBlock::gPositionedDescendantsMap) to keep track of them.
Since this static map is at block level, (positioned)inline renderers use their containing block to store
their positioned descendants.
This patch ensures that when an inline element can no longer hold positioned children, we remove them from
the inline's containing block's map. -unless the container itself can hold positioned renderers(see RenderElement::canContainAbsolutelyPositionedObjects).
