82368b17e9 Replace is_reference_error bool argument with ParseErrorType enum 
This avoids accidental coercion-to-bool when calling ReportMessage()
in the parser (e.g., from pointer types), and as a bonus makes callsites
easier to read.

522937cb49 Strip Interface class of most of its logic, make it all about Module exports 
This gets Variable and VariableProxy out of the business of worrying about
Interfaces.

At the same time, get rid of the notion of "module variables". In ES6, variables
that refer to modules will be simply be CONST bindings to module namespace
objects.

The only change in logic here is one more early error:
duplicate export names are now rejected.

c7851da4ae Introduce LanguageMode, drop StrictMode. 
This enables adding more language modes in the future.

For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to
use a sequence of language modes which are progressively stricter, but we can
express the language mode as combination of features.

For now, LanguageMode can only be "sloppy" or "strict", and there are
STATIC_ASSERTS in places which need to change when more modes are added.

LanguageMode is a bit like the old LanguageMode when "extended" mode was still
around (see https://codereview.chromium.org/8417035 and
https://codereview.chromium.org/181543002 ) except that it's transmitted through
all the layers (there's no StrictModeFlag).

f1ba8d8f86 Contribution of PowerPC port (continuation of 422063005) - AIX Common1 
Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

7d478d9621 Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) 
Reason for revert:
Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/

I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

f4fb702569 Make FlushICache NOP for Nvidia Denver CPU's. 
Denver supports a coherent cache mechanism. There is no need to clean
the D cache and invalidate I cache. MTS has to check the translation
anytime there is an I cache invalidate and this time can be saved by
making FlushICache a NOP.

The patch improves Octane by roughly 3-4% on Denver.

4fa7ae1c07 Optimize Object.seal and Object.preventExtensions 
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).
