Add support for streaming operations.

[edanor]

Streaming operations, are basically load and store operations with non-temporal hint. It might be useful to add such instructions into interface. This could be used by higher level data containers to optimize memory access patterns.

[Note to users] Please add comments if you are interested in this feature and/or if you have any hints on this idea.

Added following instructions to the interface:

• SLOAD (Streaming Load)
• MSLOAD (Masked Streaming Load)
• SSTORE (Streaming Store)
• MSSTORE (Masked Streaming Store)

By default the operation performed is the same as for regular LOAD/STORE operations.

Plugin modifications are still required.
