Add rusty stack protector(re-submit) #144879

cezarbbb · 2025-08-04T03:20:10Z

MCP: https://github.com/rust-lang/compiler-team/issues/841
This draft PR is a prototype for Rust's stack protection option.

Compared with PR Add rusty stack protector #137418, this PR has the following improvements:
Improved Rusty's stack protector's support for large variables. Now, when implicitly converting large arrays to pointers, the def_id of the function containing the array is added to the stack_protector's hashset.
