In WebKit, we have a small integer cache because calling v8::Integer::New is
slow. This patch adds a faster API for creating integers that requires the
caller to supply the v8::Isolate, saving us the work of looking up the isolate
in thread-local storage.

Some ARM architectures load 32-bit immediate constants more efficiently using movw/movt pairs rather than constant pool loads. This patch allows the assembler to generate one or the other load form at runtime depending on what is faster.

This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.

The delete operator always return true in case of indexed property. It
should return false if an indexed property can't be deleted (eg.
DontDelete attribute is set or a string object is the holder).

This is another preparation for incremental code flushing. Instead of
linking candidates using the code entry field, we use the next pointer
that is also used to link optimized functions together. Since we only
support flushing of unoptimized code, this field can be shared.
