[JSC] Implement JSON.parse source text access proposal
https://bugs.webkit.org/show_bug.cgi?id=248031
rdar://131579181
Reviewed by Yijia Huang.
This patch implements JSON.parse source text access proposal[1], which is now
stage-3.
This patch implements two major things in the proposal.
The most important part of this patch is not regressing the existing
extremely optimized JSON implementation for the fast path. Thus this
patch adds template parameter to LiteralParser and disable all the
slight changes when we are using the fast path.
1. JSON.rawJSON mechaism. Now new object type is integrated, and JSON.rawJSON
can wrap JSON text
with this object, which is a tool to inject raw JSON text into
JSON.stringify. JSON.stringify
uses held string from rawJSON-created object.
2. JSON.parse collects source information during parsing, and offer substring
of text as a third parameter
of JSON.parse reviver function.
