* config/tc-mips.c (load_register): Remove unnecessary code that was causing the high 32bits of 64bit constants to be lost. Fixes PR10503. The compiler was producing the assembler code: dli $3,0xfffffffffffff when constructing the softfloat library. Unfortunately it was being incorrectly assembled.
