This is more renaming work to comply with the naming in the public
design repository. E.g. types are called "value types" and we no longer
refer to ASTs.

No need to untag/tag flags, and we can also omit the write barrier.

Also, provide a variadic template Return function for easier use, and
refactor the underlying Return function to not use the Buffer, since
that might still be needed later (for example if trap code is generated
during CallIndirect, and the arguments to the call are stored in the
buffer).

The methods Intl.NumberFormat.prototype.v8Parse and
Intl.DateTimeFormat.prototype.v8Parse were removed several months
ago due to low usage and lack of standardization potential. This
patch removes some runtime functions used to implement them, which
were accidentally left in when they were taken out.

Update string-capitalize expected result because now it
passes all the tests in the file.
Mark fast/js/string-capitalization as failing with no_i18n.
Relanding after revert because the failure was taken care of

This patch also ports the PromiseSpecies to TF by reusing this

The test depends on tricky stack space requirements, so it stopped
working in some configurations win FLAG_min_preparse_length was removed
in commit 4a5b7e32c4.
As a workaround, pass --no-lazy until the test can be refined to work
on all configurations.

This test requires its objects to live in new space, so running it
through gc stress runs just makes it susceptible to flakiness, as
was recently seen when turning on the --harmony-string-padding
flag (which just adds an extra JS file to the bootstrapper sequence).

Original Commit Message:
eval() may introduce a scope which needs to be represented as a context at
runtime, e.g.,
eval('var x; let y; ()=>y')
introduces a variable y which needs to have a context allocated for it. However,
when traversing upwards to find the declaration context for a variable which leaks,
as the declaration of x does above, this context has to be understood to not be
a declaration context in sloppy mode.
This patch makes that distinction by introducing a different map for eval-introduced
contexts. A dynamic search for the appropriate context will continue past an eval
context to find the appropriate context. Marking contexts as eval contexts rather
than function contexts required updates in each compiler backend.

The Intl implementation included manual checks to see if they were
being called as a constructor. However, these checks are redundant,
as %FunctionRemovePrototype has already marked the functions as
un-constructable. This path removes the unnecessary checks.

The new object will hold information which is shared by all clones of a
WasmCompiledModule, e.g. the decoded asm.js offset table, and in the
future also breakpoints. From there, we can set them on each new
instantiation of any clone.
While already changing lots of the code base, I also renamed all
getters from "get_foo" to "foo", to conform to the style guide.

These benchmarks are intended to compare the overhead of async-await vs.
a naive promise implementation vs. the babel async-await transformation.
The functions in the benchmark don't do any work themselves, so results
should reflect only overhead of the chosen implementation.
Current numbers on my local machine (higher is better):
BaselineES2017-AsyncAwait(Score): 2006
BaselineNaivePromises-AsyncAwait(Score): 7470
Native-AsyncAwait(Score): 3640

Currently, to find out a Promise's status and result, one has to use the
debug context. This is for example done in Node.js. This new API is a
better replacement, also in the context of the debug context being
deprecated eventually.

We have the BytecodeIterator with next() and has_next() methods, and
pc_offset() and current() accessors.
This CL adds an interface to iterate over the opcodes or offsets in a
C++ foreach loop.

This moves the platform-specific distinction to one place, and allows
to just include assembler-inl.h instead of macro-assembler.h to get the
correct inline functions defined in assembler.h (e.g.
RelocInfo::set_target_address).
