Up until now we used int32_t for NodeId, but that was not ideal because negative values are invalid for NodeId and we use it as an array index for example in the NodeMarker class, where C++ compilers on x64 have to generate code that does proper sign extension for the indices, which is completely unnecessary.

Apparently SMMLS r, b, c, a computes r = ((a << 32) - b * c) >> 32 while the documentation is kinda misleading and states that it should compute r = a - ((b * c) >> 32) The actual behavior is kinda useless, so we drop the instruction again.

The bit counting functions provided by CompilerIntrinsics were undefined for zero, which was easily overlooked and unsafe in general. Also their implementation was kinda hacky and mostly untested. Fixed the implementation and moved the functions to base/bits.h.
