Make some dwarf_expr_context methods pure virtual
This patch changes some dwarf_expr_context to be pure virtual, as
mentioned during the discussion of an earlier patch in this series.
2016-10-21 Tom Tromey <tom@tromey.com>
* dwarf2expr.h (class dwarf_expr_context)
<get_frame_base, get_frame_cfa, get_tls_address, dwarf_call,
push_dwarf_block_entry_value, get_addr_index, get_object_address>:
Now pure virtual.
* dwarf2-frame.c (class dwarf_expr_executor)
<get_frame_base, get_frame_cfa, get_tls_address, dwarf_call,
push_dwarf_block_entry_value, get_addr_index, get_object_address>:
New methods.
<invalid>: New method.
