964cd4d7 - [AMDGPU] [NFC] Init pointers, widen mask complements (#208469)

[AMDGPU] [NFC] Init pointers, widen mask complements (#208469) - Initialize local pointers before use, silencing uninitialized local pointer warnings. - Compute mask complements at 64 bits to avoid zero-extending the result from a type to a type of greater size and dropping high bits.
