But if you need to access it very often or in "long" loops I would cache it, because 0,5kB aren't that amount of memory.

movzx  rax, bit
xor    rdx, rdx
div    64  // = BITS_IN_WORD
mov    cl, dl
movzx  rax, bit
shl    rax, cl

movzx  rax, bit
xor    rdx, rdx
div    64     // = BITS_IN_WORD
shl    rdx, 3 // *= 8 (rdx = offset of the entry in mem)
add    rdx, (pointer to the "table" in memory)
mov    rax, [rdx]

limited your GetBit function only to be able to access 2147483648 bits!

I just found it funny to not be limited and then limit the get function to int.

My question: Is there any sens in caching masks? that is: {0x0, 0x1, 0x2,... ,0x10, 0x20,....0x100000...}. It would take 0,5 kB.
