Max Howell a0763dfc2c Remove Xcode dependence from ENV.rb ...

Fixes Homebrew/homebrew#7329.
Fixes Homebrew/homebrew#7269.
Fixes Homebrew/homebrew#7236.

Also quite a lot of tidy. This should all work fine.

I think we only started referring into xcode_prefix because LLVM used to not
be linked into /usr/bin. But for sure this is no longer true. If someone out
there doesn't link cc etc. into /usr/bin then I guess we can revise this patch
but it's not something we officially supported before, it was just an
accident.

I added a test step in the init code so that a working compiler will always be
selected. This is mainly a fallback for old Xcodes. Though a comment in
another area of the code suggested Xcode 3 on 10.5 doesn't have LLVM so…
