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.

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.

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.

This avoids a pair of super-high-degree polymorphic load/store ICs, and
creates the opportunity to add more fast paths if needed.

TryTruncateFloat32ToUint64 converts a float32 to a uint64. Additionally it
provides an optional second return value which indicates whether the conversion
succeeded (i.e. float32 value was within uint64 range) or not.
I implemented the new operator on x64, arm64, and mips64. @v8-ppc-ports, can you
please take care of the ppc64 implementation of the second output?
Additionally I fixed a bug on x64 and mips64 in the implementation of
TryTruncateFloat64ToUint64. Cases where the input value was between -1 and 0
were handled incorrectly.

As discussed in person, this adds the code from v8-native-prototype into
V8 proper, guarded by GYP flags that do not build the code by default.
Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
building of this code.
An additional header file is added to and exported from the compiler
directory, src/compiler/wasm-compiler.h. This exposes a limited interface
with opaque Node and Graph types to the decoder to build TF graphs, as
well as functions to compile WASM graphs.
The mjsunit tests added are blacklisted because they fail without the
WASM object exposed to JS, which is also disabled by the build config
option.
This corresponds closely to 5981e06ebc, with some formatting fixes and moving some files into src/compiler.

* partially aborting a page with pointers between aborted pages.
* partially aborting a page with store buffer entries.
Also introduces ShouldForceOOM() which prohibits a PagedSpace from expanding.
Compaction spaces refer to the corresponding actual space.
