[Mesa-dev] [PATCH] anv: Check for VK_WHOLE_SIZE in anv_CmdFillBuffer

[Nicolas Koch]

Vulkan spec:
Size is the number of bytes to fill, and must be either a multiple of 4,
or VK_WHOLE_SIZE to fill the range from offset to the end of the buffer.
If VK_WHOLE_SIZE is used and the remaining size of the buffer is not a
multiple of 4, then the nearest smaller multiple is used.
