When initializing the ANV pipeline, one of the tasks is checking which
vertex inputs are enabled. This is done by checking if the enabled bits
in inputs_read.
But the mask to use is computed doing `(1 << (VERT_ATTRIB_GENERIC0 +
desc->location))`. The problem here is that if location is 15 or
greater, the sum is 32 or greater. But C is handling 1 as a 32-bit
integer, which means the displaced bit is out of range and thus the full
value is 0.
Rather, use BITFIELD64_BIT() to compute the mask.
