Follow up to https://reviews.llvm.org/D104808 and https://reviews.llvm.org/D105749. The only place that seems to be used is when defining __BIGGEST_ALIGNMENT__ and when choosing the alignment for the `alloca` builtin. It seems that both of these should match the `alignof(max_align_t)` which, for emscripten, is currently 8 bytes.
