X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle

making a copy of the constant pool on the stack.

Re-apply 40504, but with a fix for the segfault it caused in oggenc:
...
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.
