* Remove duplicate test
The behavior under test is verified by another file in Test262:
test/language/expressions/compound-assignment/S11.13.2_A2.1_T3.3.js
That version is preferable because it does not depend on `eval` and
because it supports both strict and non-strict mode.
* Remove overly-permissive test
By asserting only the presence of an "own" property, this test can be
satisfied from both strict mode code and non-strict mode code.
The following test verifies the presence of the "own" property and the
associated descriptor's values in strict mode:
test/language/arguments-object/10.6-13-c-3-s.js
That subsumes the semantics verified by this test, making it
superfluous. Remove the test.
* Remove overly-permissive test
By asserting only the absence of a syntax error, this test can be
satisfied from both strict mode code and non-strict mode code.
The following test verifies the runtime behavior of accessing the
property in strict mode code:
test/language/arguments-object/10.6-13-c-1-s.js
That subsumes the semantics verified by this test, making it
superfluous. Remove the test.
* Remove duplicate test
The behavior under test is verified by another file in Test262:
test/built-ins/Math/prop-desc.js
That version is preferable because it follows the test suite's
convention for testing property descriptors and because it supports both
strict and non-strict mode.
* Remove duplicate test
The behavior under test is verified by two separate files:
test/language/statements/function/line-terminator-non-strict.js
test/language/statements/function/line-terminator-strict.js
These files differ only in their usage of the `noStrict`/`onlyStrict`
metadata. Because tests are intended to be interpreted in both modes by
default, these can be expressed with a single file that does not limit
the permissible modes.
The modified tests are equally valid in strict mode and outside of
strict mode. Remove the flag which limits their use to only one of these
two contexts. Rename tests using the legacy ES5-based naming scheme to
remove the pattern which designates strict mode.
The values defined by the referenced files are not used by these tests.
This makes their inclusion superfluous, which needlessly increases the
time to execute the tests and may confuse some readers.
