Deoptimization performance degraded on x86 after AVX-512 support was added.

Test case reported in JDK-8188133 triggers pathological behavior (continuous deoptimization) in the JVM and it's >50% slower in 9 vs 8.

Profiling shows that deoptimization-related logic slowed down 2-3x and dominated by vframeArray::fill_in() where callee-saved registers are copied.
