configure.ac: supersede --enable-gallium-llvm over --enable-llvm
Currently we have extra (somewhat questionable) modularity, such that
one could build some parts with LLVM while others w/o.
That is extremely fragile, error prone and requires quite noticable
amount of code throughout.
Thus lets deprecate the gallium toggle in faviour of the generic one.
The former will throw a warning when set, and it will be overwritten by
the latter. This will allow gradual transition w/o breaking people's
scripts.
v2: Rebase, document in release notes.
