8c575ac64c [modules] Update test262 config and status file.
- Make testcfg.py ignore files ending in "_FIXTURE.js", which are not supposed
  to be tested standalone but only as imports to other modules.

- Refine test262.status to match where we are with the modules implementation.

194e418614 [test] Fix exception parsing in test262.
The _ParseException function in testcfg.py made incorrect assumptions about how
exceptions are printed (I believe it expected a trace like that produced by
Error).

fc52e32361 [parser] Allow duplicate __proto__ keys in patterns
This patch subsumes CoverInitializedNameProduction to create an ObjectLiteralProduction which is now used to report the duplicate proto error as well.

This patch also changes ObjectLiteralChecker::CheckProperty
to record an ObjectLiteralProduction error instead of
bailing out immediately. Once we realize that we're in a
pattern, we rewind the error, otherwise we report the
error.

As required by the spec.

This is a variant of what I reverted in f47e722403.
It will probably still cause a regression but now it's easier to migrate (parts of)
the current implementation to C++, which is expected to make things faster again.

In summary, Object.getOwnPropertyDescriptors can produce results which cause
Object.defineProperties() to throw, by inserting a property with an undefined
descriptor into the result object. This change to the algorithm requires that
the descriptor only be added to the result object if it is not undefined.

2907c726b2 Add errors for declarations which conflict with catch parameters.
Catch parameters are largely treated as lexical declarations in the
block which contains their body for the purposes of early syntax errors,
with some exceptions outlined in B.3.5. This patch introduces most of
those errors, except those from `eval('for (var e of ...);')` inside of
a catch with a simple parameter named 'e'.

Note that annex B.3.5 allows var declarations to conflict with simple
catch parameters, except when the variable declaration is the init of a
for-of statement.

54ce1935b5 [intl] Clean up function name handling in AddBoundMethod
AddBoundMethod, in i18n.js, returns functions all of which share the
same backing SharedFunctionInfo, which means that its calls to
InstallGetter were causing all such functions to have a single name
(that of the last caller, "get breakType").

This patch skips calling InstallGetter and instead directly calls
%DefineGetterPropertyUnchecked, which itself sets the name property
on the JSFunction instance (it knows how to do this in order to handle
getters that have computed property names).

Also takes care of a TODO having to do with the inner boundMethod:
its name is now made empty, by using a new macro that gets around
ES2015's function name inference.

Finally, removes a redundant %FunctionRemovePrototype: arrow functions
have no prototypes to begin with.

7166503f6e Do all parsing for try/catch destructuring inside the appropriate scopes
Previously, any expressions inside destructuring patterns in a catch
would be parsed in the surrounding scope, instead of in the catch's
scope. This change fixes that by entering not only the catch scope,
but also the block scope inside it.

The spec was modified to relax some requirements which implementors had not been

9bbba1441a Sloppy-mode function declarations in blocks are now hoisted appropriately.
In ES2016, function declarations nested in blocks are formally allowed. This was
never a part of ECMAScript, but was a common extension. Unfortunately
implementations differed in the exact semantics. Annex B.3.3 in the spec tries
to standardize the parts which are common to different implementations, but does
so with some fairly complicated semantics.

This CL addresses three issues related to annex B.3.3:
* When the outer function had a complex parameter list, no hoisting whatsoever was
  being performed.
* Hoisting was not blocked by parameters of the same name.
* Hoisting was not blocked by nested lexical declarations of the same name.

We had tests which checked for the second, but they were incorrectly passing due to
the first. This CL adds more complete tests.

f96be554b9 Fix order of conversions in String.prototype.substr.
The start argument must be converted to an integer before the length argument is
converted.  (Consequently, the start argument is converted even when the length
is 0.)  This matters because conversion is observable.

Also rewrite the function in a way that closely resembles the spec text.

removed after the spec was relaxed.

Also marks one test as a test262 failure rather than our failure.

9f2a18b729 TypedArray.prototype.set uses internal length property, not real one.
TypedArrays store their true length in an internal slot. This is
normally reflected in the .length property, but that property is
configurable. Algorithms which need the length of a typed array are to
use the internal slot, not the property; TypedArray.prototype.set was
not doing this.

d8147eb98c Reland: change most cases of variable redeclaration from TypeError to SyntaxError.
Reland of https://codereview.chromium.org/2048703002/

Code like `let a; eval("var a;");` should throw a SyntaxError, not a TypeError
(this caused a test262 failure.). However, the code `eval("function NaN() {}");`
should actually throw a TypeError. This patch changes most cases of
redeclaration errors from TypeError to SyntaxError. See the test
mjsunit/regress/redeclaration-error-types for a thorough analysis with spec
references.

The relevant sections of the spec are ES#sec-globaldeclarationinstantiation and
ES#sec-evaldeclarationinstantiation
