[vectorIntrinsics] RFR: Cleanup code for SVML support

[Viswanathan, Sandhya]

Hi Vladimir,

Only one comment:

In stubGenerator_x86_64.cpp, the else at line 6966 should be removed.  
6966     } else

Rest looks good.

Best Regards,
Sandhya

Considering EnableVectorSupport is turned off by default, SVML entry points should be either lazily or unconditionally initialized. 
Considering it's just caching entry point addresses I chose the latter.

Also, some cleanups (new flag to control usage of SVML stubs, renamings, etc).

Testing: jdk/incubator/vector tests

Thanks!

Best regards,
Vladimir Ivanov
