[DWARFv5] Emit new unit header format. Requesting DWARF v5 will now get you the new compile-unit and type-unit headers. llvm-dwarfdump will also recognize them. Differential Revision: http://reviews.llvm.org/D30206 llvm-svn: 296514

RUN: llvm-dwarfdump %p/Inputs/dwarfdump-header.elf-x86-64 | FileCheck %s
The input file is hand-coded assembler to generate all the units,
so we're willing to make exact checks for offsets and such.
CHECK-LABEL: .debug_info contents:
The v4 CU header.
[DWARFv5] Parse new line-table header format. The directory and file tables now have form-based content descriptors. Parse these and extract the per-directory/file records based on the descriptors. For now we support only DW_FORM_string (inline) for the path names; follow-up work will add support for indirect forms (i.e., DW_FORM_strp, strx<N>, and line_strp).
