See the reproducer and the analysis in the bug.
The fix is simple: `Matcher::match_rule_supported` should handle the predicates for current `SqrtF` and `SqrtD` match rules.
Additional testing:
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=0`, new test now passes
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=1`, new test passes
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=2`, new test passes
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=0`, `jdk/incubator/vector/` now passes
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=1`, `jdk/incubator/vector/` passes
- [x] Linux x86_32 `-XX:UseAVX=0 -XX:UseSSE=2`, `jdk/incubator/vector/` passes (some unrelated failures)
- [x] Linux x86_64, new test passes
