llvm-mirror/lib/Support/Process.cpp
Benjamin Kramer dbf33afeb8 [Support] Remove statically initialized yet dead code.
The last user of this code vanished with r223368, but this function still was
around being executed on every process start, allocating some memory and then
never being used again. No functional change.

Also avoids occasional complaints about the benign leak in this function, like
PR23037.
