New Revision: 63386

URL: http://llvm.org/viewvc/llvm-project?rev=63386&view=rev
Log:
This is case is to uncover the bug in IntrinsicLowering.cpp,
the LowerPartSet(). It didn't handle the situation correctly when 
the low, high argument values are in reverse order (low > high) 
with 'Val' type is i32 (a corner case).
