Set uv's custom data before uv_read_start

This is a behavioral difference in libuv between different platforms in
different situations. It turns out that libuv on windows will immediately
allocate a buffer instead of waiting for data to be ready. What this implies is
that we must have our custom data set on the handle before we call
uv_read_start.

I wish I knew of a way to test this, but this relies to being on the windows
platform *and* reading from a true TTY handle which only happens when this is
actually attached to a terminal. I have manually verified this works.

Closes #10645
std: IPv6 addresses are represented as eight groups of four HEXADECIMAL digits
Represent C-like enums with a plain LLVM integer, not a struct.

This is needed so that the FFI works as expected on platforms that don't
flatten aggregates the way the AMD64 ABI does, especially for `#[repr(C)]`.

This moves more of `type_of` into `trans::adt`, because the type might
or might not be an LLVM struct.
