nak: Fix 64-bit bit_count, ufind_msb, ifind_msb, find_lsb

Browse source 
Previously, these were going through nir_lower_bit_size, which handles
upscaling from lower bit sizes to 32-bit only and is incorrect for higher sizes.
This change uses nir_lower_int64 instead, which handles them properly and
correctly.
