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

[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.
