According to HSW's PRM, vol02b, the DIM instruction has the following restriction:
"Restriction : src0 must be immediate. src0 must specify the :f (F, Float) type encoding but is an immediate 64-bit DF (Double Float) value. dst must have type DF." This commit allows to upload the immediate 64-bit DF value to the source of a DIM instruction even when it is of float type encoding.
