[Lldb-commits] [scan-build] Fix reported dead store, logic error and api bugs

[Apelete Seketeli via lldb-commits]

Hello,

Here are a few changes that try to address some logic error bugs
reported by running scan-build over the LLDB code base.

I have no background in compiler technology and I may have been trying
to fix false positives; here is a quick overview of what scan-build
reported, let me know if the fixes are relevant:

Bug Group: Dead store
Bug Type: Dead assignment
Files: source/Plugins/SymbolFile/DWARF/DWARFASTParserJava.cpp
    
Bug Group: Logic error
Bug Type: Called C++ object pointer is null
Files: source/Plugins/ABI/SysV-mips64/ABISysV_mips64.cpp
    
Bug Group: Logic error
Bug Type: Called C++ object pointer is null
Files: source/API/SBThread.cpp
    
Bug group: Logic error

Bug Group: API
