Fix DWARF5 regression

Default initialize enum flags to 0

2017-02-21T16:48:49+00:00

... so that we don't need to do it manually, and potentially forget.
For example, this allows to do:

  my_flags flags;

  ...

  flags |= some_flag;

gdb/ChangeLog:

	* common/enum-flags.h (enum_flags::enum_flags): Initialize
	m_enum_value to 0 in default constructor.

DWARF-5: NEWS

2017-02-20T20:02:51+00:00

	* NEWS (Changes since GDB 7.12): Add DWARF-5.

DWARF-5: DW_FORM_data16

2017-02-20T20:02:20+00:00

DWARF-5 has new form DW_FORM_data16.  The problem is that GDB cannot pass
16-byte constant as a constant value as that would require GDB to use GCC
extension __int128.

Formerly such data was coded as DW_FORM_block* so GDB still decodes
DW_FORM_data16 like DW_FORM_block*.

gdb/ChangeLog
2017-02-20  Jan Kratochvil  

	* dwarf2read.c (skip_one_die, read_attribute_value)
	(dwarf2_const_value_attr, dump_die_shallow)
	(dwarf2_get_attr_constant_value, dwarf2_fetch_constant_bytes)
	(skip_form_bytes, attr_form_is_constant): Handle DW_FORM_data16.
