Overview

Lane by lane vector compare.

Simple vector compares

Linear lane by lane (x0 compared to y0, etc) comparison between x and y buffers.

These "Simple Vector Comparison" instrinsics return one bit per compare where the result of lane 0 is placed in the LSB. All others return one word return one word per lane (with word size according to the input parameter).

Note that data from xbuff is the left operand and data from ybuff is the right operand. The only exceptions are "gt[N]" and "le[N]" where the buffers are swapped.
