Akira Hatanaka 8edf8f317b [ObjC][ARC] Let ARC optimizer bail out if the number of pointer states 
it keeps track of becomes too large

ARC optimizer does a top-down and a bottom-up traversal of the whole
function to pair up retain and release instructions and remove them.
This can be expensive if the number of instructions in the function and
pointer states it tracks are large since it has to look at each pointer
state and determine whether the instruction being visited can
potentially use the pointer.

This patch adds a command line option that sets a limit to the number of
pointers it tracks.
