Saleem Abdulrasool 2bd1262a32 ARM: introduce llvm.arm.undefined intrinsic
This intrinsic permits the emission of platform specific undefined sequences.
ARM has reserved the 0xde opcode which takes a single integer parameter (ignored
by the CPU).  This permits the operating system to implement custom behaviour on
this trap.  The llvm.arm.undefined intrinsic is meant to provide a means for
generating the target specific behaviour from the frontend.  This is
particularly useful for Windows on ARM which has made use of a series of these
special opcodes.
