53fdf9d192 Use a different map to distinguish eval contexts
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.

b88d96c73a [intl] Remove new.target check in Intl functions and method
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.

081ac37048 [wasm] Introduce WasmSharedModuleData and refactor other objects
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.

9feefafa66 [js-perf-test] Add a basic async-await microbenchmark
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

28432588c2 [api] add API for Promise status and result.

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.

21a85c4a03 [wasm] Always provide a wasm instance object at runtime
When executing wasm code for testing, we did not create a
WasmInstanceObject and link it to the generated code. This required
some special handling at runtime (mainly for stack trace generation).
This CL always provides the WasmInstanceObject, such that e.g. function
names can be resolved the usual way.
The module bytes referenced by the WasmCompiledModule linked with the
WasmInstanceObject do not hold a valid wasm module yet. Instead, we
just add the bytes we need, and make the objects in WasmModule point to
those bytes (currently only used for function names). Those bytes will
not be parsed at runtime anyway.

The scenario here: the asm function fails asm validation,

the script object that we cache on the script object. This wrapper
is context-dependent and causes the code serializer to choke.
