Justin Lebar 291abd3ebb Speed up Function::isIntrinsic() by adding a bit to GlobalValue. NFC ... Summary: Previously isIntrinsic() called getName(). This involves a hashtable lookup, so is nontrivially expensive. And isIntrinsic() is called frequently, particularly by dyn_cast<IntrinsicInstr>. This patch steals a bit of IntID and uses that to store whether or not getName() starts with "llvm."
