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 switches sloppy-mode code from legacy const semantics
to ES2015 semantics. It is unknown how much of the web will be
broken by this; likely the patch will have to be reverted before
a branch happens.

Even though the change is ES6 spec compliant, we decided to revert
to be consistent with other browsers and work on fixing the spec.
Original issue's description:
> Make dates default to the local timezone if none specified
>
> In ES5, dates were supposed to default to UTC if no timezone was specified. However, this changed in ES6, which specified that dates should be in the local timezone if no timezone was specified. This CL updates our behavior to match that part of the ES6 spec.

Add a flag to explicitly filter scripts in ignition and use it for the test262
variant. The previous approach of overloading ignition-filter meant that only
top-level code was getting compiled through ignition.

This makes it explicit when the --ignition-filter pattern should be
applied to the script name instead of the function name by using a
proper "s:{name}" pattern. It also hardcodes it to be a prefix match
instead of an exact match, because that is all we need for test262.

Adds an ignition variant to the test runner and adds support to test262 for
filtering such that only test scripts (not the test harness) get run by
the interpreter.

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.

The current implemention breaks sloppy mode code that uses function
declarations inside blocks at top-level. Work is ongoing on a patch
to fix this issue, but in the meantime it seems reasonable to move
the feature out of staging.

Now run-tests.py understands "suite/foo/bar" with forward slashes for
command-line test selection on all test suites on all platforms.
Previously, file-based suites like mjsunit also accepted "mjsunit/foo\bar";
that behavior is sacrificed here in favor of unification. For the cctest
suite, OTOH, it wasn't possible on Windows to select specific tests at all.

This is a change for ES2015. Date objects have mutable state, so having
a mutable prototype is bad for SES requirements, and it is an
inconsistency from the typical ES2015 class style of objects
