move `tools.mk` to run-make apparently I missed some tests in the last commit. Rather than having dozens of tests use the long version, use the short version in `run-make` and the long version in `run-make-fulldeps` (which is now only three tests)

rustc: Continue to tweak "std internal symbols" In investigating [an issue][1] with `panic_implementation` defined in an executable that's optimized I once again got to rethinking a bit about the `rustc_std_internal_symbol` attribute as well as weak lang items. We've sort of been non-stop tweaking these items ever since their inception, and this continues to the trend. The crux of the bug was that in the reachability we have a [different branch][2] for non-library builds which meant that weak lang items (and std internal symbols) weren't considered reachable, causing them to get eliminiated by ThinLTO passes. The fix was to basically tweak that branch to consider these symbols to ensure that they're propagated all the way to the linker. Along the way I've attempted to erode the distinction between std internal symbols and weak lang items by having weak lang items automatically configure fields of `CodegenFnAttrs`. That way most code no longer even considers weak lang items and they're simply considered normal functions with attributes about the ABI. In the end this fixes the final comment of #51342 [1]: https://github.com/rust-lang/rust/issues/51342#issuecomment-414368019 [2]: https://github.com/rust-lang/rust/blob/35bf1ae25799a4e62131159f052e0a3cbd27c960/src/librustc/middle/reachable.rs#L225-L238

Upgrade Emscripten targets to use upstream LLVM backend - Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

# only-wasm32-bare
use ignore directives for run-make tests This makes the tests easier to read, and makes it possible to tell which tests aren't being run on the host platform. Fixes #56704.
