LLVM will insert calls to the stack protector functions "__stack_chk_fail" and "__stack_chk_guard" into code in native object files. Some platforms include these symbols directly in libc, but at least historically these have been provided in libssp.so on illumos and Solaris systems. Include "-lssp" in the arguments to the linker when building for those targets.
It appears to codegen slightly more efficiently with `split_at` taking two slices at once, rather than slicing across different calls.
It can try to keep its allocation by converting the inner `Box` to `Vec`, using `clone_into` on the bytes, then convert back to `Box`.
Despite OS differences, they're all just `Vec<u8>` inside, so we can just forward `clone_into` calls to that optimized implementation.
Small tweaks in ToOwned::clone_into - `<[T]>::clone_into` is slightly more optimized. - `CStr::clone_into` is new, letting it reuse its allocation. - `OsStr::clone_into` now forwards to the underlying slice/`Vec`.

Miri leak check: memory reachable through globals is not leaked Also make Miri memory dump prettier by sharing more code with MIR dumping, and fix a bug where the Miri memory dump would print some allocations twice. r? @oli-obk Miri PR: rust-lang/miri#1301
…nits, r=alexcrichton Keep codegen units unmerged when building compiler builtins Make it possible to control how mono items are partitioned into code generation units, when compiling the compiler builtins, by retaining the original partitioning. Helps with rust-lang#48625, rust-lang#61063, rust-lang#67960, rust-lang#70489. r? @alexcrichton
…tolnay Use assoc int submodules Bumping some submodules to the commits their masters currently point at. The main point of this is to get the associated integer/float constant documentation updates that were recently merged to them: * rust-lang/nomicon#207 * rust-lang/rust-by-example#1327 * rust-lang/stdarch#848 But for some, a few more changes slipped by that happened to be in the master branch of these submodules. r? @dtolnay
…=dtolnay Don't import integer and float modules, use assoc consts 2 Follow up to rust-lang#70777. I missed quite a lot of places. Partially because I wanted to keep the size of the last PR down, and partially because my regexes were not good enough :) r? @dtolnay
