[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.

void main()
{
    typedef int int_t = 42;
    int_t i;
    assert(i == int_t.init);
}
