Description
JDK-8280076 added the ability to print the IR with a PrintIdeal compile command based on the IGV printing phases. This provides the basis for extending the IR framework to support IR matching after different compilation phases.

This could be done by introducing a phase attribute to the @IR annotation.

https://github.com/robcasloz/zgc/commit/781fe22fbf77b72b3a0aa72be58cf4665240caef adds Q&D support for selecting the IR phase globally (i.e. for all tests). It could perhaps be used as a starting point for this RFE.
