Extend the vcmp/fcmp LLVM IR instructions to take vectors as arguments
and, if so, to return a vector of boolean as a result;
Extend the select LLVM IR instruction to allow you to specify a result
type which is a vector of boolean, in which case the result will be an
element-wise selection instead of choosing one vector or the other; and
Update LangRef.html to describe these changes.
This patch was contributed by Preston Gurd!
