[PATCH] D37118: [ARM] Tidy-up ARMAsmParser. NFC.

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

Why not use MCRegisterInfo::getSubReg for this purpose, thus avoiding repeating information that's already present in ARMRegisterInfo.td? `MRI->getSubReg(QReg, ARM::dsub_0)` should replace the functionality of getDRegFromQReg.
