Subject: [PATCH] MicroBlaze correct the const high double immediate value

With this patch the loading of the DI mode immediate values will be
using REAL_VALUE_FROM_CONST_DOUBLE and REAL_VALUE_TO_TARGET_DOUBLE
functions, as CONST_DOUBLE_HIGH was returning the sign extension value
even of the unsigned long long constants also

ChangeLog:

2016-02-03  Nagaraju Mekala  <nagaraju.mekala@xilinx.com>
            Ajit Agarwal  <ajitkum@xilinx.com>

	* microblaze.c (print_operand): Use REAL_VALUE_FROM_CONST_DOUBLE &
	  REAL_VALUE_TO_TARGET_DOUBLE
	* long.c (new): Added new testcase
