Initialize/Register LTO passes to enable flags like -print-after=<lto-pass>

There already have two "dead" functions, initialize{IPO|IPA}, defined for 
similar purpose. I decide not to call these two functions for two reasons:
  o. they don't cover all LTO passes (which will soon be separated into IPO 
     and post-IPO passes)
  o. We have not yet figured out the right passes and the ordering for IPO 
     and post-IPO stages, meaning this change is only for the time being.

Since LTO passes are registered, we are now able to print IR before and 
after particular point.

For OSX users:
--------------
  "...-Wl,-mllvm -Wl,-print-after=<pass-name>" will print IR after the
  specified pass.

For Other UNIX with GNU gold linker:
------------------------------------
  "-Wl,-plugin-opt=-print-after=<pass-name>" should work.
  (NOTE: no need for "-Wl,-mllvm")

  Strip "-Wl," if flags are fed directly to linker instead of clang/clang++.

[mips] Use ADDu instead of OR to copy general purpose registers. Also, delete
the InstAlias pattern which maps "move" to OR to resolve ambiguity in
MatchTable.
