David Blaikie 892742907f DWARFVerifier: Verbosely dump DIEs in verifier reports
Seems helpful when you're dealing with invalid/problematic DWARF. Some
diagnostic messages are probably redundant with the verbose dumping and
could be simplified with this.

Xing GUO 2d35092cd2 [DWARFYAML] Make the include_directories, file_names and opcodes fields of the line table optional.
This patch makes the include_directories, file_names and opcodes fields
of the line table optional. This helps us simplify some tests.

Xing GUO 290e399f96 [DWARFYAML] Add support for emitting multiple abbrev tables.
This patch adds support for emitting multiple abbrev tables. Currently,
compilation units will always reference the first abbrev table.

Greg Clayton e1de85f9f4 Add verification for DW_AT_decl_file and DW_AT_call_file.
LTO builds have been creating invalid DWARF and one of the errors was a file index that was out of bounds. "llvm-dwarfdump --verify" will check all file indexes for line tables already, but there are no checks for the validity of file indexes in attributes.

The verification will verify if there is a DW_AT_decl_file/DW_AT_call_file that:
- there is a line table for the compile unit
- the file index is valid
- the encoding is appropriate

Tests are added that test all of the above conditions.
