ARM: Teach A15 SDOptimizer to properly handle D-reg by-lane.
These instructions, such as vmul.f32, require the second source operand to
be in D0-D15 rather than the full D0-D31. When optimizing, make sure to
account for that by constraining the register class of a replacement virtual
register to be compatible with the virtual register(s) it's replacing.
I've been unsuccessful in creating a non-fragile regression test. This issue
was detected by the LLVM nightly test suite running on an A15 (Bullet).
