Stephen Hines 8267e7d456 LLDB JIT needs android vector passing rules. 
Summary:
Looking into some recent issues with LLDBs expression parser highlighted that upstream clang passes vectors types differently to Android Open Source Project's clang for Arm Android targets.
This patch reflects the changes present in the AOSP and allows LLDB's JIT expression evaluation to work correctly for Arm Android targets when passing vectors.

This is submitted with consent of the original author Stephen Hines.
