This removes the ability to generate stub code via the full-fledged
compiler pipeline that parses and analyzes JavaScript source code.
Generation of stub code has been moved to a lower-level entry point.

- proxies-with-unscopables needed updating of trap names
- proxies-symbols doesn't make sense any more: it tested symbol fitering/
blacklisting, but Proxies interact with Symbols just fine according to
the current spec.

This CL tries to correctly support the following:
- stringifying a proxy,
- stringifying with a proxy as replacer (callable or arraylike),
- stringifying with a replacer that returns a proxy,
- parsing with a callable proxy as reviver,
- parsing with a reviver that inserts proxies into the object,
- and whatever else you can imagine.
This also fixes some bugs observable without proxies.

The test Run_Wasm_StoreMem_offset_oob contained an I64STORE instruction,
which is not yet implemented on 32 bit platforms. I turned off those
parts of the test on 32 bit platforms which contain I64 instructions.

Debug evaluate no longer writes back changes to the replicated
context chain to the original after execution. Changes to the
global object or script contexts still stick. Calling functions
that bind to the original context chain also have their expected
side effects.
As far as I can tell, DevTools is not interested in modifying
local variable values. Modifying global variable values still
works as expected. However, I have not yet removed the old
implementation, but merely keep it behind a flag.

Move replacements out of virtual object. Replacements are
global to the graph and are not dependent on the virtual

This uses the same pipeline entry function for all three assemblers
currently supported by TurboFan. The Pipeline::GenerateCodeForCodeStub

This CL makes proxy-related error messages more accurate and verbose.
(Exception: those used in deprecated functions in v8natives.js.) Some of
the old error messages were simply wrong.
On the side, fix ShouldThrow semantics of JSProxy::SetPrototype and
JSProxy::DefineOwnProperty.

The parser reads one character beyond EOF to have an additional source
position that the rewriter can use to insert the implicit return
statement at the end of a script. If we break at that return statement,
we need to be able to translate the source position to line and
column number.

Bugfixes and improvements in escape analysis include:
* Handling of ObjectIsSmi (non-escaping)
* Handling of nested phi replacements
* Handling of phis with arity > 2
* Resilience against effectful nodes dangling from start
* Allocations escape now, if non-const load/store is performed
* Fixed a bug where non-allocated objects where tracked
* Allow fixed double arrays to be tracked

Debug-evaluate used to resolve stack variables that shadow
context variables incorrectly, since the stack variable is
not visible in the context chain.
To fix this, we limit local variables accessible by debug-
evaluate to the ones directly referenced inside the function.
What is not referenced by the function itself, is considered
optimized out and not accessible by debug-evaluate.
To achieve this, we duplicate the entire context chain up to
the native context, and write back changes after debug-
evaluate. Changes to the original context chain will however
be overwritten. This already happens for catch and block
scopes though.
Also fix a crash caused by declaring variables inside debug-
evaluate.

Since the parser now desugars super constructor calls to simple
primitives, we can also easily optimize those in fullcodegen w/
just a few simple lines of native code per architecture. This
code in particular should be fast, so it seems worth the code
in fullcodegen.

A couple of the Intl tests made calls to getDefaultTimeZone(), which
doesn't exist in V8; however, these were not core to the test. Rather
than marking the whole test as failing, just comment out that
unimportant part of the test.

The %GetPrototype runtime function does a lot more than the
GetSuperConstructor specified in ES6 12.3.5.2. So this introduces a
proper %_GetSuperConstructor instead with support in TurboFan.

Before this change traps always returned a 32 bit word in tests. With this
change traps return either a 32 bit word or a64 bit word, depending on the size
of the actual return value of the test.
Additionally this CL implements the wasm instructions I64SCONVERTF32,
I64UCONVERTF32, I64SCONVERTF64, and I64UCONVERTF64.
