'equals()' expression replaceable by 'Objects.equals()' expression

Reports expressions that can be replaced with a call to java.util.Objects#equals.

Example:

void f(Object a, Object b) { boolean result = a != null && a.equals(b); }
void f(Object a, Object b) { boolean result = Objects.equals(a, b); }

Replacing expressions like a != null && a.equals(b) with Objects.equals(a, b) slightly changes the semantics. Use the Highlight expressions like 'a != null && a.equals(b)' option to enable or disable this behavior.

This inspection only reports if the language level of the project or module is 7 or higher.
