f7428bc397 Fix macos_dump_syms when __eh_frame is included in the dSYM file.
macho_reader assumes that every section in a segment exists, or none of the
sections exist in the file (for dSYM files).

https://reviews.llvm.org/D94460?id=315965 added __eh_frame section to the
__TEXT segments in dSYM files. All the other sections are removed, but still
have non-zero size in the header. macho_reader only looks at `fileoff` and
`filesize` fields to determine the size of the segment, but it looks at `addr`
and `size` to determine the size of the section, therefore it determines that
the sections would not fit in the segment and refused to parse the file.

In this case the removed sections all have offset == 0. Ignore such cases.

275e6d46a4 Make forward reference DIEs cross compilation units.
Before this change, forward_ref_die_to_func is always empty.
Because forward reference DIEs could cross compilation units,
forward_ref_die_to_func is moved into FilePrivate.
By using "grep "name omitted" sym | wc -l", the number of functions
with no name is reduced from 26951 to 203 if forward reference only is
allowed within CU. It's reduced from 203 to 6 if crossing compilation
units is allowed.

   ?foo@@YAXXZ.llvm.1304071520971994875

Strip such suffixes in order to demangle the names.

f195f0a55e Add core_handler and pid2md into git ignore
`core_handler` and `pid2md` are always untracked after `make`. They are
the output of build. We should ignore them.

```
Untracked files:
  (use "git add <file>..." to include in what will be committed)
    src/tools/linux/core_handler/core_handler
    src/tools/linux/pid2md/pid2md

f794d083dc Dwarf5 fixes [5 of 5]: Recognize dwp version 5.
Fifth of 5 small patches to fix various breakpad issues found
while testing dump_syms of DWARF v5 in ChromeOS.

DWARF v5 introduces a new dwp version, version 5. The current
dwp reader only recognizes versions 1 & 2 as valid dwp versions. This
CL fixes that.

3c528da94c Dwarf5 fixes [4 of 5]: Skip processing Dwarf5 type units.
Fourth of 5 small patches to fix various breakpad issues found
while testing dump_syms on DWARF v5 in ChromeOS.

Dwarfv5 adds many new Type Unit sections to debug information. Since
these only contain type information, they are of no interest to
dump_syms.  This CL gets dump_syms to skip trying to process the
type unit sections.  Without this CL, dump_syms takes ~ 3 hours to
process the DWARF v5 Chrome binary.  With this CL, dump_syms takes
~ 8 minutes to process the DWARF v5 Chrome binary (about the same
time as it takes for DWARF v4).

This CL also adds a test case to verify that type units are being
skipped.

646f0f4920 Dwarf5 fixes [3 of 5]: Fix bugs reading .debug_line_str.
Third of 5 small patches to fix various breakpad issues found
while testing dump_syms on DWARF v5 in ChromeOS.

The offset into the line table was being incorrectly added to the
.debug_string and debug_line_str sections in the code for reading
the line table.  It was also skipping trying to read the line table
if the .debug_line_str section was present.  This CL fixes these
issues.

ac9712d9b4 Dwarf5 fixes [2 of 5]: Handle .debug_str_offsets properly.
Second of 5 small patches to fix various breakpad issues found
while testing dump_syms on DWARF v5 in ChromeOS.

This patch adds code to properly find & parse the
DW_AT_str_offsets_base attribute, and use it to handle strings
of the forms DW_FORM_strx, DW_FORM_strx1..DW_FORM_strx4 This is the
largest of the DWARF5 fixes.  It also includes a unittest to test
using a string offset.
