intel/compiler: Print hex representation along with floating point value

While encoding the immediate floating point values in instruction we use
values upto precision 9, but while disassembling, we print precision to
6 places, which round up the value and gives wrong interpretation for
encoded immediate constant.

To avoid misinterpretation of encoded immediate values in instruction
and disassembled output, print hex representation along with floating
point value which can be used by assembler in future.
