versions. This commit adapts NODE_MODULE_VERSION for V8 8.5.

Patch V8 (compiler/js-heap-broker.cc) to remove the use of an optional
property, which is a fairly new C++ feature, since that requires a newer
XCode version than the minimum requirement in BUILDING.md and thus
breaks CI.

Patch V8 (wasm/wasm-module.cc) to remove const qualifier from type
passed to template call of `OwnedVector::Of`. Xcode 8 can't convert
'OwnedVector<unsigned char>' to 'OwnedVector<const unsigned char>' when
returning from a function (which is likely a bug on Xcode, considering
this worked on the prior version of Xcode as well as newer versions).
This workaround shouldn't affect the application, since the const
qualifier is preserved in the AsmJsOffsetInformation::encoded_offset_.

There's also a V8 test passing a const-qualified type to ::Of, but since
we don't test V8 on Xcode 8, it should be fine to leave it as is.

Original commit message:

    [coverage] remove the last continuation range before synthetic return

    Rather than only removing the continuation range for the last return
    statement prior to a synthetic return statement, remove the
    continuation tracking for whatever statement occurs prior to the
    synthetic return.
