Clemens Backes fa056cd088 [utils] Move {WhichPowerOf2} to base::bits ... {WhichPowerOf2} is basically the same as {CountTrailingZeros}, with a restriction to powers of two. Since it does not use or depend on any v8 internals, it can be moved to src/base/bits.h. This CL also changes the implementation to use the CTZ builtin if available, and falls back to popcnt otherwise. Drive-by: Make it constexpr, and rename to {WhichPowerOfTwo}.
