Adds a blacklist of tests which are currently unsupported or broken in Ignition to
the mjsunit and test262 test status.
Also removes --ignition-script-filter flag, and adds a
--ignition_fallback_on_eval_and_catch flag which fallsback to fullcodegen for
functions which call eval or contain a catch block.

Since enabling destructuring already implies enabling default parameters,
there's not a good way to separate these two. Luckily, they're both
feature-complete (save for destructuring assignment).
This causes us to pass an additional 24 test262 tests.

Many places in the JavaScript standard library are changed in ES2015 from
getting an integer using ToUint32 to using ToLength. This patch stages
the flag turning on those new semantics.

When == is invoked on a Symbol or SIMD vector and an object, the object should
be converted to a primitive with ToPrimitive and then compared again. This means,
for example, that for a Symbol or SIMD vector s, s == Object(s). This patch makes
that change in the implementation of ==. Only the runtime function needed to be
changed, as the code stubs and compiler specializations don't operate on Symbols
or SIMD vectors, and on these types, a fallback to the runtime function is always
used.

This patch prohibits lexical bindings from being called 'let', even in
sloppy mode, following the ES2015 specification. The change affects
multiple cases of lexical bindings, including simple let/const declarations
and both kinds of for loops. var and legacy const bindings still permit
the name to be let, including in destructuring cases. Tests are added to
verify, though some cases are commented out since they led to (pre-existing)
crashes.

ES2015 made a change vs ES5, where the "lastIndex" property of a
RegExp (which can be modified by a user to start the next search at
a different location) is cast to an integer with ToLength rather
than ToInteger. The main difference is on negative numbers, and
this is tested by test262. This patch implements that change on
RegExps and enables the test262 test now that it passes.

This removes the duplicate property check from object literals.
Instead we repurpose the ObjectLiteralChecker into two cases, implemented
by two subclasses to ObjectLiteralCheckerBase called ObjectLiteralChecker
and ClassLiteralChecker.
The object literal checker now only checks for duplicate __proto__ fields in
object literals.
The class literal checker checks for duplicate constructors, non constructor
fields named constructor as well as static properties named prototype.

environment on little-endian host using simulator.
- In order to have i18n support working on big-endian target, the icudt46b.dat and
icudt46b_dat.S files should be generated and upstreamed to ICU repo.
- The mjsunit 'nans' test is endian dependent, it is skipped for mips target.
