RFR: 8360559: Optimize Math.sinh for x86 64 bit platforms

[Mohamed Issa]

The goal of this PR is to implement an x86_64 intrinsic for java.lang.Math.sinh() using libm. There is a new set of micro-benchmarks are included to check the performance of specific input value ranges to help prevent regressions in the future.

The command to run all range specific micro-benchmarks is posted below.

`make test TEST="micro:SinhPerf.SinhPerfRanges"`

The results of all tests posted below were captured with an [Intel® Xeon 8488C](https://advisor.cloudzero.com/aws/ec2/r7i.metal-24xl) using [OpenJDK v26-b4](https://github.com/openjdk/jdk/releases/tag/jdk-26%2B4) as the baseline version.

For performance data collected with the new built in range micro-benchmark, see the table below. Each result is the mean of 8 individual runs, and the input ranges used match those from the original Java implementation. Overall, the intrinsic provides an an average uplift of 64% when input values fall into the middle three ranges where heavy computation is required. However, very small inputs and very large inputs show drops of 74% and 66% respectively.

| (-INF, -710.48], [710.48, INF)           | 959296                                    | 313839                                    | 0.33x       |

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