Rollup merge of rust-lang#46354 - Mark-Simulacrum:alt-try, r=alexcrichton

Deploy builds both with asserts enabled and asserts disabled to CI.

This also removes uploads to the 'try' bucket, and instead dumps
everything into the two rustc-builds and rustc-builds-alt buckets. This
makes lives easier, as there is only one location for a given "type" of
build, and since we have the git commit hash in the filenames, this is
fine; we won't run into uploads of the same commit.

cc @aidanhs -- this will break crater's logic for downloading `try#xxx` commits since the try bucket won't be uploaded into
