Auto merge of #21282 - Aatch:init-memzero, r=alexcrichton
LLVM gets overwhelmed when presented with a zeroinitializer for a large type. In unoptimised builds, it generates a long sequence of stores to memory. In optmised builds, it manages to generate a standard memset of zero values, but takes a long time doing so. Call out to the `llvm.memset` function to zero out the memory instead. Fixes #21264
