commit 3d567982aca11c85a7fa31f13046de3271d3afc8
Author: Tom Tromey <tromey@redhat.com>

    implement support for "enum class"
    
    This adds support for the C++11 "enum class" feature.  This is
    PR c++/15246.
    
    I chose to use the existing TYPE_DECLARED_CLASS rather than introduce
    a new type code.  This seemed both simple and clear to me.
    
    I made overloading support for the new enum types strict.  This is how
    it works in C++; and it didn't seem like an undue burden to keep this,
    particularly because enum constants are printed symbolically by gdb.
    
    Built and regtested on x86-64 Fedora 20.

    constify value_aggregate_elt
    
    While working on another patch I realized that value_aggregate_elt's
    "name" parameter ought to be const.  This patch implements this.

    handle DW_AT_type on an enumeration
    
    DWARF allows an enumeration type to have a DW_AT_type.  GDB doesn't
    recognize this, but there is a patch to change GCC to emit it, and a
    DWARF proposal to further allow an enum type with a DW_AT_type to omit
    the DW_AT_byte_size.  This patch changes gdb to implement this.
    
    Built and regtested on x86-64 Fedora 20.

    	* gdb.dwarf2/enum-type.exp: New file.
