void IntrinsicLowering::LowerIntrinsicCall ( CallInst * CI )

Replace a call to the specified intrinsic function.

If an intrinsic function must be implemented by the code generator (such as va_start), this function should print a message and abort.

Otherwise, if an intrinsic function call can be lowered, the code to implement it (often a call to a non-intrinsic function) is inserted after the call instruction and the call is deleted. The caller must be capable of handling this kind of change.
