[AST] Add a fast path to ConstantArrayType::getNumAddressingBits(). - This fast path is almost 100% effective on real code, and lets us avoid multiple allocations of 128-bit APSInt objects in the common case. - As with any overflow-check-skipping-code, I'd appreciate someone double checking my logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177183 91177308-0d34-0410-b5e6-96231b3b80d8
