[PATCH] Fix VGATHER* operand constraints Add earlyclobber constaints to prevent input register being allocated as the output register because, according to Intel spec [1], "If any pair of the index, mask, or destination registers are the same, this instruction results a UD fault." --- [1] http://software.intel.com/sites/default/files/319433-014.pdf git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183327 91177308-0d34-0410-b5e6-96231b3b80d8
