During property reconfiguring ensure that the first map that gets new descriptors is the one that owns the whole descriptor array.

This is necessary to guarantee that the whole descriptor would be marked, otherwise DescriptorArray pretenuring would cause crashes.

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.

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 https://github.com/WebAssembly/v8-native-prototype/commit/5981e06ebc9b1e578831d03100f17ebb77970ee0, with some formatting fixes and moving some files into src/compiler.

No need to have an indirection to get to the initial JSArray maps from
the native context; we only cache the fast elements maps anyway, so
those could live on the native context directly. This will also
integrate nicely with the load/store propagation in TurboFan (once we
propagate the immutable flag for FieldAccess as well).

Drive-by-fix: Also don't embed any of the initial JSArray maps in
TurboFan generated code when allocating a new JSArray, but instead
always load the appropriate map from the native context.  This way
we ensure that we never leak a reference to one of those maps and
its as efficient as embedding a constant map.
