	* 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.
