title: Disable thumbEE instructions in Arm Compiler 6.14
body: <p>ThumbEE(T32EE) was introduced in ARMv7 and removed in ARMv8.
  In 2011 ARM deprecated any use of the ThumbEE instruction set.
  However, Arm Compiler 6.14 use ThumbEE instructions when we compile code with --thumb.</p>
  <p>Is there a way the compiler not to use thumbEE instructions?</p>
