llvm-mirror/lib/Target/Hexagon/HexagonSubtarget.h
Chandler Carruth a98c778194 Sort includes for all of the .h files under the 'lib' tree. These were
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]
