This commit implements the AsmParser for fnstart, fnend, cantunwind, personality, handlerdata, pad, setfp, save, and vsave directives. This commit fixes some minor issue in the ARMELFStreamer: * The switch back to corresponding section after the .fnend directive. * Emit the unwind opcode while processing .fnend directive if there is no .handlerdata directive. * Emit the unwind opcode to .ARM.extab while processing .handlerdata even if .personality directive does not exist. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181603 91177308-0d34-0410-b5e6-96231b3b80d8
