std: Clean out deprecated APIs

Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that
are deprecated in the 1.8 release are sticking around for the rest of this
cycle.

Some notable changes are:

* The `dynamic_lib` module was moved into `rustc_back` as the compiler still
  relies on a few bits and pieces.
* The `DebugTuple` formatter now special-cases an empty struct name with only
  one field to append a trailing comma.
