Drop obsolete compiler fallback in stdenv

This code originated in a slightly different form in 8e88b22fd1ec65a344ce6e4facd6dad4b415b2ad:

https://github.com/Homebrew/homebrew/blob/8e88b22fd1ec65a344ce6e4facd6dad4b415b2ad/Library/Homebrew/extend/ENV.rb#L30-L32

Back then, MacOS.default_compiler could return nil, which meant
ENV.compiler could do the same. This code was carried forward as the
surrounding code changed. At this point it should be unreachable.

ENV/shared: handle untapped e.g. gcc48 formula.

In this case we need to handle the throwing on an exception when
attempting to initialize the gcc48 Formula object.

This initialization should be unnecessary if the core GCC is already
installed and rescued if not.

brew-test-bot: handle failing devel requirements.
Superenv: determine_optflags should return a string

This is saved in HOMEBREW_OPTFLAGS and later mutated by
ENV.universal_binary, so if this returns nil the sub will fail.
uade: add new HEAD resource

bencode-tools isn't well-known or used enough to justify its own
formula at this point in time, but it's a dependency for the HEAD
version of UADE.
