I ''guess'' it was removed when switching from Xcode 6.x to 7.x; ''if
that's true'', the
* last version ''with'' GAS would be 6.4 (with cctools-870, Apple LLVM
6.1.0, clang-602.0.53), the
* first version ''without'' GAS would be 7.0 (with cctools-877.5, Apple
LLVM 7.0.0, clang-700.0.72).
Xcode versions 7.0 - 7.2.1 require at least Yosemite, Xcode 7.3 and later
El Capitan.

It seems the Xcode and "Apple LLVM" ''major'' version numbers are
(meanwhile) derived from the ''minor'' version of upstream LLVM (with some
fuzz), while the versions in "clang-''x.y.z''" are more weird (''x'' = 100
* Xcode major version + ''n'' with a "random" ''n < 10'', ''y'' being a
small minor version number and ''z'' being the patchlevel).
