Survey: Is somebody using the -enable-*/-disable-* command line option pairs?

Some command line options have a switch to turn them on and off, 
e.g. -enable-asserts and -disable-asserts.
These option pairs are only available for a handful of ldc2 
command line options. Every option defined inside the LLVM 
framework does not offer an opposite switch, e.g. 
-disable-red-zone exists but not -enable-red-zone.

With LLVM 3.7, an overhaul of the option code has started. In 
consequence, the implementation for the ldc2 option pairs does 
not work anymore. I have an idea how to fix it but this includes 
a fair amount of work.

Before I start fixing the code I would like to know if someone is 
using these options.

If not then I will deprecated these options and remove them by 
the time LLVM 3.7 is released (will be in late autumn).
