AFAIK, Walter's suggestion is not supported by LLVM. Currently LLVM removes
code that uses uninitialized value. To work it around LDC will need to
initialize variables initialized with void and provide an different way to
declare uninitialized variables. Likely not a problem, but results in minor
fragmentation of language. I believe LDC way will have a priority, because DMD
is not really about performance anyway, so default initialized variables for it
are good enough.
