Squiz/NonExecutableCode: remove redundant line

$prev is already defined in exactly the same way on line 66. No need to re-define it.

Squiz/NonExecutableCode: only ignore inline statements when PHP allows them

Aside from T_EXIT, PHP (prior to PHP 8.0) does not allow for the inline use of the other tokens this sniff registers.
While using those tokens inline would result in a parse error, that is not the concern of this sniff.

By ignoring these, the sniff causes false negatives.

This commit makes the sniff more selective and only ignores inline statements for tokens which are allowed in inline statements.

Includes unit test.

Squiz/NonExecutableCode: bug fix - allow for all logic operators

The sniff, as it was, only allowed for or and || logical operators before a termination expression, not for and, && or xor, while PHP allows these too.

See: https://3v4l.org/OWS4n#veol

Fixed now.

Includes unit tests.

Squiz/NonExecutableCode: bug fix - expressions in ternary

The T_EXIT token can be used in ternaries without affecting code after the ternary expression.

See: https://3v4l.org/oMWuA#veol

Fixed now.

Includes unit test.

Fixes #2857

Squiz/NonExecutableCode: bug fix - expressions after PHP 7.0/7.4 null coalesce (equals)

PHP 7.0 introduced the null coalesce operator.
PHP 7.4 introduced the null coalesce equals operator.

The T_EXIT token can be used in combination with those without affecting the code directly following it.

See: https://3v4l.org/C218d#veol

Fixed now.

Includes unit test.

Squiz/NonExecutableCode: bug fix - expressions in PHP 7.4 arrow functions

PHP 7.4 introduced arrow functions. The T_EXIT token can be used in those without affecting the code following it.

See: https://3v4l.org/gSrt4#veol

Fixed now.

Includes unit test.

Squiz/NonExecutableCode: bug fix - PHP 8.0 inline throw expressions

PHP 8.0 introduced the ability to use throw as an expression instead of as a statement.
Ref: https://wiki.php.net/rfc/throw_expression

When used as an expression, the throw does not necessarily affect the code after it.

See: https://3v4l.org/AmMf2

Fixed now.

Includes unit tests.

Fixes #3592

FYI: this fix is included in today's PHP_CodeSniffer 3.8.0 release.

As per #3932, development on PHP_CodeSniffer will continue in the PHPCSStandards/PHP_CodeSniffer repository. If you want to stay informed, you may want to start "watching" that repo (or watching releases from that repo).
