[jdk17u-dev] RFR: 8008243: Zero: Implement fast bytecodes

[Aleksey Shipilev]

Clean backport to improve Zero performance. The rationale for backport is the same as for mainline. Given that Zero is used to implement the JVM on emerging platforms that are still rather slow themselves, it makes sense to make Zero quantifiably faster. Even 10% improvement means more than 2 hours a day worth of CPU time.

This backport requires a follow-up to fix some platforms:
  [8277485](https://bugs.openjdk.org/browse/JDK-8277485): Zero: Fix _fast_{i,f}access_0 bytecodes handling 

We still have `RewriteBytecodes` to get the original behavior if more bugs appear.

Additional testing:
 - [x] Linux x86_64 Zero `make bootcycle-images`
