RFR: 8265900: Use pattern matching for instanceof at module jdk.compiler(part 2)

[Guoxiong Li]

Hi all,

This series of patches update the code of the module jdk.compiler by using the pattern matching for instanceof.

This patch would revise the following packages:

com.sun.tools.javac.code
com.sun.tools.javac.comp
com.sun.tools.javac.jvm
com.sun.tools.javac.parser
com.sun.tools.javac.processing


Thank you for taking the time to review.
