Rollup merge of #147526 - bjorn3:alloc_shim_weak_shape, r=petrochenkov,RalfJung

Move computation of allocator shim contents to cg_ssa

In the future this should make it easier to use weak symbols for the allocator shim on platforms that properly support weak symbols. And it would allow reusing the allocator shim code for handling default implementations of the upcoming externally implementable items feature on platforms that don't properly support weak symbols.

In addition to make this possible, the alloc error handler is now handled in a way such that it is possible to avoid using the allocator shim when liballoc is compiled without `no_global_oom_handling` if you use `#[alloc_error_handler]`. Previously this was only possible if you avoided liballoc entirely or compiled it with `no_global_oom_handling`. You still need to avoid libstd and to define the symbol that indicates that avoiding the allocator shim is unstable.

rust-analyzer is a language server that provides IDE functionality for writing Rust programs. You can use it with any editor that supports the Language Server Protocol (VS Code, Vim, Emacs, Zed, etc).

rust-analyzer features include go-to-definition, find-all-references, refactorings and code completion. rust-analyzer also supports integrated formatting (with rustfmt) and integrated diagnostics (with rustc and clippy).

Internally, rust-analyzer is structured as a set of libraries for analyzing Rust code. See Architecture in the manual.
