Michael Munday 7582494e06 cmd/compile: add s390x intrinsics for Ceil, Floor, Round and Trunc 
Ceil, Floor and Trunc are pre-existing intrinsics. Round is a new
function and has been added as an intrinsic in this CL. All of the
functions can be implemented as a single 'LOAD FP INTEGER'
instruction, FIDBR, on s390x.
