Additionally removed the `arrow-function` feature for
test/language/eval-code/direct/new.target-fn.js as it is not testing
arrow-functions, but they are mentioned in the preamble.

Because these files contain syntax errors, the code they contain is not
intended to be executed, and the runtime semantics are therefore
irrelevant. Simplify the files by removing the unnecessary code.

This patch changes tabs to spaces for newly added tests.

Early errors may result from parsing the source text of a test file, but
they may also result from parsing some other source text as referenced
through the ES2015 module syntax. The latter form of early error is not
necessarily detectable by ECMAScript parsers, however. Because of this,
the label "early" is not sufficiently precise for all Test262 consumers
to correctly interpret all tests.

Update the "phase" name of "early" to "parse" for all those negative
tests that describe errors resulting from parsing of the file's source
text directly. A forthcoming commit will update the remaining tests to
use a "phase" name that is more specific to module resolution.

* Accessing `ta[0]` throws a TypeError.

* Fix array indices starting at 0 and property references

* Fix classfields templates for properly checking static propnames.

* Generate tests

* `assert.equal` is not defined

* Add missing includes

* Generate tests

* typo s/Avalue/42/

* fix whitespace

* Add missing var for strict mode

* Expand generated class fields tests for forbidden computed property name values

* derived classes have access to private names in base classes, if private names are in scope

This pattern makes expectations more explicit by making test files more
literal.

Tests doesn't use async functionality and don't call $DONE, so remove
"async" flag:
- src/params/error/async-gen-named-func-expr.template
- test/language/expressions/async-generator/params-named-dflt-abrupt.js
- test/language/expressions/async-generator/params-named-dflt-ref-later.js
- test/language/expressions/async-generator/params-named-dflt-ref-self.js

Intl.PluralRules.prototype is no longer a Intl.Prototype instance:
- test/intl402/PluralRules/prototype/prototype.js

Intl.PluralRules throws an error when called as a function:
- test/intl402/PluralRules/undefined-newtarget-throws.js

Module namespace objects call OrdinaryDelete for symbol properties:
- test/language/module-code/namespace/internals/delete-non-exported.js

Async generators no longer retrieves "done" property twice:
- src/async-generators/yield-star-async-next.case
- src/async-generators/yield-star-async-return.case
- src/async-generators/yield-star-async-throw.case

Minor units of CLF is 4, so we need to test with maximumFractionDigits=3
to get an error:
- test/intl402/NumberFormat/dft-currency-mnfd-range-check-mxfd.js

DateTimeFormat.prototype.formatToParts length property was changed from
0 to 1:
- test/intl402/DateTimeFormat/prototype/formatToParts/length.js

minimumSignificantDigits and maximumSignificantDigits properties are
only retrieved once:
- test/intl402/NumberFormat/11.1.1_32.js

Fixes #877
Ref #872

Cyclic dependencies are no longer an error per
https://github.com/tc39/ecma262/pull/783.
