RFR: 8276025: Hotspot's libsvml.so may conflict with user dependency

[Sandhya Viswanathan]

This patch removes conflicts with libsvml.so distributed with Intel's MKL library:
  Renames exported symbols from __svml to __jsvml.
  Renames library from libsvml.so to libjsvml.so.
  Updates the stubGenerator_x86_64.cpp  accordingly to load libjsvml.so and the renamed symbols.
  Updates tests to look for the new library.

Please review.

Best Regards,
Sandhya
