mesa: Shrink the size of the enum string lookup struct.
Since it's only used for debug information, we can misalign the struct and save the disk space. Another 19k on a 64-bit build. v2: Make a compiler.h macro to only use the attribute if we know we can. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
