[asimiklit.work at gmail.com]

From: Andrii Simiklit <andrii.simiklit at globallogic.com>

1. main/texcompress_etc.c:1314:12:
    warning: ‘*((void *)&dst+2)’ may be used uninitialized in this function
2. main/texcompress_etc.c:1354:12:
    warning: ‘*((void *)&dst+2)’ may be used uninitialized in this function
3. main/texcompress_etc.c:1293:12:
    warning: ‘dst’ may be used uninitialized in this function
4. main/texcompress_etc.c:1335:12:
    warning: ‘dst’ may be used uninitialized in this function
5. main/texcompress_etc.c:1460:12:
    warning: ‘*((void *)&dst+1)’ may be used uninitialized in this function

v2: Fixed by adding the unreachable case to the etc2_rgb8_fetch_texel
       ( Eric Engestrom <eric.engestrom at intel.com> )
    Changes for warning 'pixerrorcolorbest' were removed.
