LOG: Move llvm::array_lenghtof to llvm/ADT/STLArrayExtras.h

This moves the dependency of several files on include/llvm/ADT/STLExtras.h to
the much shorter llvm/ADT/STLArrayExtras.h

Differential Revision: https://reviews.llvm.org/D118342

Added: 
    llvm/include/llvm/ADT/STLArrayExtras.h

Modified: 
    llvm/include/llvm/ADT/STLExtras.h
    llvm/lib/Support/ARMAttributeParser.cpp
    llvm/lib/Support/Signals.cpp
    llvm/lib/Support/Triple.cpp
    llvm/lib/Support/raw_ostream.cpp

Removed:
