Since the enums get optimized down to 1 byte long, the bits set in the usize member don't align with the enums on big-endian machines. Avoid this issue by shrinking the integer member to the same size as the enums.

Fix double_check tests on big-endian targets Since the enums get optimized down to 1 byte long, the bits set in the `usize` member don't align with the `enum` values on big-endian machines. Avoid this issue by shrinking the integer member to the same size as the enums.

…ichton Add powerpc- and powerpc64-unknown-linux-musl targets Add targets for musl on 32-bit and 64-bit powerpc. This requires some ABI fixes, as musl [uses the ELFv2 ABI on regardless of endianness](http://git.musl-libc.org/cgit/musl/tree/configure?id=8084d6ab57cdb0b8f328d3cdbad3b9d09eaaee04#n638). At the moment, powerpc64 support requires [an LLVM patch](https://reviews.llvm.org/D52013) to select the correct ABI; or I can add [a patch to Rust's LLVM backend](smaeul@e8eaa2a) to always choose the right ABI. Both architectures are able to run an extended bootstrap, and with some test fixes (e.g. rust-lang#55561), there are no architecture-dependent test failures on powerpc64 (most failures in `src/test` are existing musl-host-related issues).
