Default HasSetDirective to true, since most targets have it. The targets that claim to not have it probably do, or it is spelled differently. These include Blackfin, Mips, Alpha, and PIC16. All of these except pic16 are normal ELF targets, so they almost certainly have it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94585 91177308-0d34-0410-b5e6-96231b3b80d8
