RFR: 8353686: Optimize Math.cbrt for x86 64 bit platforms [v2]

[Mohamed Issa]

> The goal of this PR is to implement an x86_64 intrinsic for java.lang.Math.cbrt() using libm.
> 
> The results of all tests posted below were captured with an [Intel® Xeon 6761P](https://www.intel.com/content/www/us/en/products/sku/241842/intel-xeon-6761p-processor-336m-cache-2-50-ghz/specifications.html) using [OpenJDK v25-b15](https://github.com/openjdk/jdk/releases/tag/jdk-25%2B15) as the baseline version.
> 
> For performance data collected with the built in **cbrt** micro-benchmark, see the table below. Each result is the mean of 8 individual runs. Overall, the intrinsic provides a performance uplift of 41%.

> | Benchmark        | Throughput with baseline (op/s) | Throughput with intrinsic (op/s) | Speedup |

> 
> Finally, the `jtreg:test/jdk/java/lang/Math/CubeRootTests.java` test passed with the changes.

Mohamed Issa has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains four commits:

 - Merge branch 'openjdk:master' into user/missa-prime/cbrt
 - Change coeff_table alignment from 4 bytes to 16 bytes to conform with movapd instruction
 - Merge branch 'master' into user/missa-prime/cbrt
 - x86_64 intrinsic for cbrt using libm
