gas: Use udata for DW_AT_high_pc when emitting DWARF4
For DWARF4 DW_AT_high_pc can be expressed as constant offset from
DW_AT_low_pc which saves a relocation. Use DW_FORM_udate (uleb128)
to keep the constant value as small as possible.
gas/ChangeLog:
* dwarf2dbg.c (out_debug_abbrev): When DWARF2_VERSION >= 4, use
DW_FORM_udata for DW_AT_high_pc.
(out_debug_info): Use emit_leb128_expr for DW_AT_high_pc, when
DWARF2_VERSION >= 4.
* read.c (emit_leb128_exp): No longer static.
* read.h (emit_leb128_exp): Define.
