159bcc7bad Improve test precision
Previously, some tests verified two independent concerns simultaneously:
syntactic validity and runtime completion value. The former is relevant
for ECMAScript runtimes and parsers alike, but the latter is only
observable by runtimes.

Express expectations regarding syntactic validity using literal program
code so they can be used by parsers. Maintain the original tests which
rely on eval in order to preserve coverage for statement completion
values.

136110378b Rename negative test "phase" for parsing
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.

81d00def42 Force "early error" tests to fail if evaluated
This pattern makes expectations more explicit by making test files more
literal.

Ensure that early errors restricting labelled function declarations
within WithStatement and IfStatement are honored. Rename existing tests
to match the specification's spelling.

4dc81d3788 Add tests for tail-call optimization
ECMAScript 2015 introduced tail call optimization for function calls
occuring in a number of positions in the grammar. Assert expected
behavior by triggering a large (but configurable) number of recursive
function calls in these positions. Compliant runtimes will execute such
programs without error; non-compliant runtimes are expected to fail
these tests by throwing an error or crashing when system resources are
exhausted.

e62d43c815 Update tests according to ES2016 draft semantics
The ES2016 draft further refines the completion values for `if` and
`with` statements. Two tests must be removed outright because the
completion value in those cases is no longer accessible from the
runtime.

407b8964ce Add tests for ES2015 completion reform
In order to facilitate proper tail calls, ES2015 modified the completion
value of a number of statements.

These tests use `eval` to verify the new values.

92890e6723 Remove $FAIL function
This function is equivalent to `$ERROR` (which is automatically included
in test environments). Remove the harness file that defines the
function, remove references to the file from test `includes` lists, and
update scripts to instead invoke the `$ERROR` function.
