MipsSEInstrInfo class defines for internal purpose unconditional branches as Mips::B nad Mips:J even in case of microMIPS code generation. Under some conditions that leads to the bug - for rather long branch which fits to Mips jump instruction offset size, but does not fit to microMIPS jump offset size, we generate §short§ branch and later show an error 'out of range PC16 fixup' after chek in the isBranchOffsetInRange routine.
