Pete Cooper 0ec73f6e98 SimplifyCFG now predicts some conditional branches to true or false depending on previous branch on same comparison operands. ...

For example, 

if (a == b) {
    if (a > b) // this is false
    
Fixes some of the issues on <rdar://problem/10554090>

BasicInliner.cpp

Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180.
