[svn r323] Branching out of inline asm works. Renamed emit_finallyblocks to DtoFinallyBlocks and moved to llvmhelpers. Added enclosingtryfinally to AsmBlockStatement, so branches out of asm blocks respect finallys. Refactored some GotoStatement code into DtoGoto.

    auto s = Cin.get();
    Cout("putting name").newline;
    Cout (s).newline;
