llvm-6502/lib/Target/R600/AMDILNIDevice.h
Chandler Carruth 58a2cbef4a Resort the #include lines in include/... and lib/... with the
utils/sort_includes.py script.

Most of these are updating the new R600 target and fixing up a few
regressions that have creeped in since the last time I sorted the
includes.
