6340864: Implement vectorization optimizations in hotspot-server
Added asm encoding and mach nodes for vector arithmetic instructions on x86.
Added new emit_*_arith() helper methods to simplify code for asm encoding.
Added few missing parts in superword code which already supports vector
arithmetic (added code for vector MulI and URShiftI).
Note: these changes did not implement vectorization to get a sum of array's
elements as bug's description asked - it needs more work.
Tested with compiler and java/lang regression tests, CTW and also provided
vector arithmetic tests. I am converting those tests into compiler regression
tests which will be included into these changes.
