201d1e56bb Teach basicaa that memset's modref set is at worst "mod" and never
contains "ref".

Enhance DSE to use a modref query instead of a store-specific hack
to generalize the "ignore may-alias stores" optimization to handle
memset and memcpy.

0f53f592ad 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.

8e0c7b5287 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.
