This PR will focus only on the handling of the ACC_STRICT flag during classfile parsing.

Prior state of this PR restored. This PR only updates the policy around the VM's handling of ACC_STRICT and adds corresponding tests. David's PR for 8266950 covers the refactoring and cleanup inside the HotSpot code from only having support for a single floating-point mode.
