MIPS: LLVMLinux: Fix a 'cast to type not present in union' error.
Remove a cast to the 'mips16e_instruction' union inside an if condition and instead do an assignment to a local 'union mips16e_instruction' variable's 'full' member before the if statement and use this variable in the if condition. This is the error message reported by clang: arch/mips/kernel/branch.c:38:8: error: cast to union type from type 'unsigned short' not present in union if (((union mips16e_instruction)inst).ri.opcode ^ ~~~~ The changed code can be compiled successfully by both gcc and clang.
