b15a082d56 Fix implementation of bit count functions. 
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.

948a0dea44 When marking dependent code for deoptimization print the group that is being deoptimized. 
Otherwise it is impossible to figure out from the --trace-deoptimization output what is going on.

2c6d5cfb27 Old space cannot be assumed to be iterable between GCs, even if swept precisely. 
This is because allocation folding can cause uninitialized and hence uniterable fragments. Trying to inspect them causes SizeFromMap() crashes.
