Description
For n = 1, 2, 4, 8 and 16 read sizeof(halfn) bytes of data from address (p + (offset * n)). The data read
is interpreted as a halfn value. The halfn value read is converted to a floatn value and the floatn value
is returned.
The address computed as (p + (offset * n)) must be aligned to sizeof(halfn) bytes.
For n = 3, vloada_half3 reads a half3 from address (p + (offset * 4)) and returns a float3. The address
computed as (p + (offset * 4)) must be aligned to sizeof (half) * 4 bytes.
