Check if we can handle the arguments of a call (and therefore the call) in fast-isel before emitting code. If the program bails after code was emitted, then it could lead to the stack being adjusted more than once (two CALLSEQ_BEGINs emitted) but being adjuste back only once after the call. This leads to general badness and gnashing of teeth. <rdar://problem/11050630>
