Unrolled build for rust-lang#126502

Rollup merge of rust-lang#126502 - cuviper:dump-mir-exclude-alloc-bytes, r=estebank Ignore allocation bytes in some mir-opt tests This adds `rustc -Zdump-mir-exclude-alloc-bytes` to skip writing allocation bytes in MIR dumps, and applies it to tests that were failing on s390x due to its big-endian byte order. Fixes rust-lang#126261
