Lang Hames 3d478aee8e Return early from getUnconditionalBranchTargetOpValue if the branch target is ... an MCExpr, in order to avoid writing an encoded zero value in the immediate field. When getUnconditionalBranchTargetOpValue is called with an MCExpr target, we don't know what the final immediate field value should be. We shouldn't explicitly set the immediate field to an encoded zero value as zero is encoded with a non-zero bit pattern. This leads to bits being set that pollute the final immediate value. The nature of the encoding is such that the polluted bits only affect very large immediate values, explaining why this hasn't caused problems earlier.
