<pre>As of r335682, llvm asserts when running InstCombine over
test/Transforms/EarlyCSE/invariant.start.ll. Running "./bin/opt -basicaa
-early-cse -instcombine" also asserts in the same way.
$ ./bin/opt -instcombine -S -o -
$(srcs)/test/Transforms/EarlyCSE/invariant.start.ll
Assertion failed: (ArgIdx == 2 && "Invalid argument index"), function
getForArgument, file
/Users/vsk/src/llvm.org-master/llvm/lib/Analysis/MemoryLocation.cpp, line 140.
