LOG: [DSE,MemorySSA] Remove some duplicated test functions.

Some tests from multibuild-malloc-free.ll do not actually use malloc or
free and where split out to multiblock-throwing.ll, but not removed from
the original file. This patch cleans that up. It also moves @test22 to
simple.ll, because it does not involve multiple blocks.

Added: 
    

Modified: 
    llvm/test/Transforms/DeadStoreElimination/MSSA/multiblock-malloc-free.ll
    llvm/test/Transforms/DeadStoreElimination/MSSA/multiblock-throwing.ll
    llvm/test/Transforms/DeadStoreElimination/MSSA/simple.ll

Removed:
