RFR: 8265783: Create a separate library for x86 Intel SVML assembly intrinsics [v2]

[Sandhya Viswanathan]

> Intel Short Vector Math Library (SVML) based intrinsics in native x86 assembly provide optimized implementation for Vector API transcendental and trigonometric methods.
> These methods are built into a separate library instead of being part of libjvm.so or jvm.dll.
> 
> The following changes are made:
>    The source for these methods is placed in the jdk.incubator.vector module under src/jdk.incubator.vector/linux/native/libsvml and src/jdk.incubator.vector/windows/native/libsvml.
>    The assembly source files are named as “*.S” and include files are named as “*.S.inc”.
>    The corresponding build script is placed at make/modules/jdk.incubator.vector/Lib.gmk.
>    Changes are made to build system to support dependency tracking for assembly files with includes.
>    The built native libraries (libsvml.so/svml.dll) are placed in bin directory of JDK on Windows and lib directory of JDK on Linux.
>    The C2 JIT uses the dll_load and dll_lookup to get the addresses of optimized methods from this library.
> 
> Build system changes and module library build scripts are contributed by Magnus (magnus.ihse.bursie at oracle.com).
> 
> This work is part of second round of incubation of the Vector API.
