Wow, great additions, thanks!
I think the check could be a target feature, or it could be true to all AArch64 targets.
@kristof.beyls isn't FMA always faster on vanilla AArch64?
@t.p.northover same for Apple's hardware, I think, no?
cheers,

Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:7624
+ case AArch64Subtarget::ThunderX2T99:
+ case AArch64Subtarget::ThunderXT88:
+ if (VT.isFloatingPoint() && VT.isVector())
----------------
This smells like a target feature. :)
