[PATCH] D62300: [AVR] Fix incorrect source regclass of LDWRdPtr

[Jim Lin via Phabricator via llvm-commits]

Herald added a project: LLVM.

LDWRdPtr would be expanded to ld+ldd. ldd only accepts the pointer register is Y or Z. 
So the register class of pointer of LDWRdPtr should be PTRDISPREGS instead of PTRREGS.
