  --> https://bugs.freedesktop.org/attachment.cgi?id=134056&action=edit
Updated version with changes related only to *_supported functions.

I have deleted all changes not realted to *_supported functions.

Change in src/gallium/auxiliary/util/u_format.c:util_format_is_supported -
check that value of format in correct range (<PIPE_FORMAT_COUNT).

Changes in src/gallium/drivers/{r600,radeonsi} - check for holes in format
values.
