Not quite a mass replacement as I've used OS X and Mac OS X where
describing specific older versions and added compatibility methods
for things in the DSL.
On systems prior to 10.9, formulae that use CVS as a download source
check whether the installed Xcode already provides CVS to avoid adding
a dependency on the `cvs` formula. Unfortunately, if no Xcode is
installed the check fails with
undefined method `<' for nil:NilClass
causing the formula to become unloadable. This in turn causes some taps
to be untappable since #396 added the `readall` check on `tap`.
Closes#508.
This primarily benefits CLT-only systems where invoking the `xcodebuild`
wrapper in `/usr/bin` will fail (twice) with the following message:
xcode-select: error: tool 'xcodebuild' requires Xcode, but active
developer directory '/Library/Developer/CommandLineTools' is a command
line tools instance
Closes#198.

Due to a typo, the range of LLVM build versions 2066 to 2325 were never
matched and thus Xcode 3.2.0 could never be inferred from that. (Only
relevant for legacy systems. Doesn't seem to have impacted any users.)
Resolves an issue where xcode-select output with a terminal slash leads
to superenv failing to strip system library paths from ccld-style
invocations.
FixesHomebrew/homebrew#49731. Discussion in Homebrew/homebrew#50154.
Provide `OS::Mac.prerelease?` for pre-release checks and use it where
appropriate. This should simplify updating the test once a new OS X
release lands.
This also fixes a bug in `BuildError#dump`, where an empty warning
message was printed on El Capitan after a failed from-source build,
because the check there and the one in `check_for_unsupported_osx` were
out of sync.
ClosesHomebrew/homebrew#45257.
