Sam Parker c98a8a09b5 [HardwareLoops] Loop guard intrinsic to recognise zext ... If a loop count was initially represented by a 32b unsigned int in C then the hardware-loop pass can recognise the loop guard and insert the llvm.test.set.loop.iterations intrinsic. If this was instead a unsigned short/char then clang inserts a zext instruction to expand the loop count to an i32. This patch adds the necessary pattern matching to enable the use of lvm.test.set.loop.iterations in those cases.
