      Even if the subprogram is going to use AT_specification, emit DW_AT_MIPS_linkage_name. This helps gdb and fixes var-path-expr.exp regression reported by gdb testsuite.

      Gracefully handle invalid live ranges. Fix PR9831. · eaa6ed1a
      Jakob Stoklund Olesen authored
      Register coalescing can sometimes create live ranges that end in the middle of a
      basic block without any killing instruction. When SplitKit detects this, it will
      repair the live range by shrinking it to its uses.
      
      Live range splitting also needs to know about this. When the range shrinks so
      much that it becomes allocatable, live range splitting fails because it can't
      find a good split point. It is paranoid about making progress, so an allocatable
      range is considered an error.
      
      The coalescer should really not be creating these bad live ranges. They appear
      when coalescing dead copies.

      If the front end has emitted llvm.dbg.cu and other debug info anchors (clang does it now) then use them directly. This saves one scan of entire module, to collect debug info, which in turns saves few machine cycles at compile time.

      Other parts of the SelectionDAG framework assume that targets use their pointer type for vector indices.  Make the vector unrolling code respect that.
