Clear clears the given bit in a []uintptr bitset.

ClearInterval clears the bits at all positions in [startIdx, limitIdx) in a []uintptr bitset.

NewClearBits creates a []uintptr bitset with capacity for at least nBit bits, and all bits clear.

NewNonzeroWordScanner returns a NonzeroWordScanner for the given bitset, along with the position of the first bit.

NewSetBits creates a []uintptr bitset with capacity for at least nBit bits, and all bits at positions [0, nBit) set.

Set sets the given bit in a []uintptr bitset.

SetInterval sets the bits at all positions in [startIdx, limitIdx) in a []uintptr bitset.

Test returns true iff the given bit is set.

BitsPerWord is the number of bits in a machine word.

Log2BitsPerWord is log_2(BitsPerWord).

NonzeroWordScanner iterates over and clears the set bits in a bitset, with the somewhat unusual precondition that the number of nonzero words is known in advance.
