8374516: -version asserts with "-XX:+UseAESCTRIntrinsics -XX:-UseAES": "need AES instructions and misaligned SSE support" in generate_counterMode_AESCrypt_Parallel()

[rm-gh-8]

Backporting JDK-8374516: -version asserts with "-XX:+UseAESCTRIntrinsics -XX:-UseAES": "need AES instructions and misaligned SSE support" in generate_counterMode_AESCrypt_Parallel().

This PR fixes an x86 JVM startup crash by disabling UseAESCTRIntrinsics when UseAES is disabled (e.g. -XX:+UseAESCTRIntrinsics -XX:-UseAES).

For parity with Oracle JDK.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/hotspot/jtreg/compiler/cpuflags/TestUseAESCTRIntrinsicsWithUseAESDisabled.java

Results:

windows-x64-specific-test.log
macos-aarch64-specific-test.log
linux-x64-specific-test.log
linux-aarch64-specific-test.log

/approval request for backport of JDK-8374516: -version asserts with "-XX:+UseAESCTRIntrinsics -XX:-UseAES": "need AES instructions and misaligned SSE support" in generate_counterMode_AESCrypt_Parallel().

This PR fixes an x86 JVM startup crash by disabling UseAESCTRIntrinsics when UseAES is disabled (e.g. -XX:+UseAESCTRIntrinsics -XX:-UseAES).

For parity with Oracle JDK.

Low risk — narrowly scoped to x86 AES flag resolution, only disables an unusable intrinsic, and behaves identically for all normal flag combinations.
