Changes in directory llvm/include/llvm/Support:
CommandLine.h updated: 1.55 -> 1.56
---
Log message:
Add external definitions for commonly-used template specializations and add
anchor methods to others. This eliminates the vtable/template method bloat
in .o files that defining a cl::opt used to impose (~4K per .o file for one
cp::opt<unsigned>).
