RFR: 8265128: [REDO] Optimize Vector API slice and unslice operations

[Sandhya Viswanathan]

All the slice and unslice variants that take more than one argument can benefit from already intrinsic methods on similar lines as slice(origin) and unslice(origin).

Changes include:
 * Rewrite Vector API slice/unslice using already intrinsic methods
 * Fix in library_call.cpp:inline_preconditions_checkIndex() to not modify control if intrinsification fails
 * Vector API conversion tests thresholds adjustment
