[mips] Add checks for alignment and maximum displacements for most of the branch instructions for mips and micromips instruction sets thus avoiding the situation of generating branches to undesired locations if offsets cannot be encoded. This patch also checks if a fixup cannot be applied and returns a fatal error if that's the case. llvm-svn: 197223
