Fix build for LLVM >= r74640 Some LLVM objects now take a 'Context' to make multi-threaded apps easier. Since we're not multi-threaded it's safe to use llvm::getGlobalContext() which gives us the same behavior as we had before.

module mini.arrays19;

extern(C) int printf(char*, ...);

void main()
{
  bool var = ([] is null);
  assert(var);
}
