Dan Gohman 1dcad96dc6 Don't split critical edges during the AddUsersIfInteresting phase ...

of LSR. This makes the AddUsersIfInteresting phase of LSR a pure
analysis instead of a phase that potentially does CFG modifications.

The conditions where this code would actually perform a split are
rare, and in the cases where it actually would do a split the split
is usually undone by CodeGenPrepare, and in cases where splits
actually survive into codegen, they appear to hurt more often than
they help.

Use a safer iterator interface and get rid of std C++ library misuse.

Real fix for PR3549, by using caching for predecessor counts in addition to the predecessors themselves. This halves the time

I should definitely read make docs someday :(
