[PATCH] D39150: [globalisel][tablegen] Import stores and allow GISel to automatically substitute zero regs like WZR/XZR/$zero.

There's two patches in one here and I'm going to try and extract the stores portion of the patch and commit that separately if I can find a reasonable way to do so without causing regressions. The main purpose of this review is to determine whether we agree it's safe to allow the new GIZeroRegister on GPR32/GPR64/GPR32all/GPR64all. I think it's probably ok, but I don't feel I have sufficient knowledge of AArch64 to make such a sweeping change without someone more familiar with it giving it the go ahead.
