Summary: In microMIPS, labels need to know whether they are on code or data. This is indicated with STO_MIPS_MICROMIPS and can be inferred by being followed by instructions. For empty basic blocks, we can ensure this by emitting the .insn directive after the label. Also, this fixes some failures in our out-of-tree microMIPS buildbots, for the exception handling regression tests under: SingleSource/Regression/C++/EH Reviewers: dsanders Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D9530 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236815 91177308-0d34-0410-b5e6-96231b3b80d8
