This PR implements zeros and population count instructions: `clz`/`clzw`/`ctz`/`ctzw`/`cpop`/`cpopw`.
New C2 instructions are covered by the following JTREG tests: - test/hotspot/jtreg/compiler/codegen/Test6823354.java - test/hotspot/jtreg/compiler/codegen/Test7100757.java - test/hotspot/jtreg/compiler/codegen/Test8005033.java
Hotspot and jdk tier1 tests on QEMU (with and without UseRVB) are passed without new failures.
