Patch for Mips direct object generation.
When WriteFragmentData() case FT_align called Asm.getBackend().writeNopData() is called, nothing is done since Mips implementation of writeNopData just returned "true". For some reason this has not caused problems in 32 bit mode, but in 64 bit mode it caused an assert when processing multiple function units. The test case included will assert without this patch. It runs twice with different flags to prevent false positives due to changes in code generation over time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160084 91177308-0d34-0410-b5e6-96231b3b80d8
