Subject: [PATCH] GBE: fix 3-component vector's astype macros.

According to OpenCL spec,

For 3-component vector data types, the size of the data type is 4 * sizeof(component). This
means that a 3-component vector data type will be aligned to a 4 * sizeof(component)
boundary. The vload3 and vstore3 built-in functions can be used to read and write, respectively,
3-component vector data types from an array of packed scalar data type.
