29dd2a1569 two changes to DSE that shouldn't affect anything: 
1. Don't bother trying to optimize:

lifetime.end(ptr)
store(ptr)

as it is undefined, and therefore shouldn't exist.

2. Move the 'storing a loaded pointer' xform up, simplifying
  the may-aliased store code.

f5eece615c Fix the encoding of VLD4-dup alignment. 
The only reasonable way I could find to do this is to provide an alternate
version of the addrmode6 operand with a different encoding function.  Use it
for all the VLD-dup instructions for the sake of consistency.
