This adds support for analyzing the instruction with the !annotation
"auto-init" in order to generate a more user-friendly remark.

For now, support the store size, and whether it's atomic/volatile.

Example:

  auto-init.c:4:7: remark: Store inserted by -ftrivial-auto-var-init.Store size: 4 bytes. [-Rpass-missed=annotation-remarks]
    int var;
        ^
