Subject: [PATCH 21/53] [PATCH 21/53] [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
