[AArch64] Enable PostRAScheduler for AArch64 generic build. Disable post-ra scheduler for perturbed tests to appease the bots and to preserve the history of the tests. http://reviews.llvm.org/D15652 llvm-svn: 256158

[AArch64] Support selecting STNP. We could go through the load/store optimizer and match STNP where we would have matched a nontemporal-annotated STP, but that's not reliable enough, as an opportunistic optimization. Insetad, we can guarantee emitting STNP, by matching them at ISel. Since there are no single-input nontemporal stores, we have to resort to some high-bits-extracting trickery to generate an STNP from a plain store. Also, we need to support another, LDP/STP-specific addressing mode, base + signed scaled 7-bit immediate offset. For now, only match the base. Let's make it smart separately. Part of PR24086. llvm-svn: 247231

[AArch64] Match FI+offset in STNP addressing mode. First, we need to teach isFrameOffsetLegal about STNP. It already knew about the STP/LDP variants, but those were probably never exercised, because it's only the load/store optimizer that generates STP/LDP, and the only user of the method is frame lowering, which runs earlier. The STP/LDP cases were wrong: they didn't take into account the fact that they return two results, not one, so the immediate offset will be the 4th operand, not the 3rd.

[AArch64] Support selecting STNP. We could go through the load/store optimizer and match STNP where we would have matched a nontemporal-annotated STP, but that's not reliable enough, as an opportunistic optimization. Insetad, we can guarantee emitting STNP, by matching them at ISel. Since there are no single-input nontemporal stores, we have to resort to some high-bits-extracting trickery to generate an STNP from a plain store. Also, we need to support another, LDP/STP-specific addressing mode, base + signed scaled 7-bit immediate offset. For now, only match the base. Let's make it smart separately.
