e3aafccae9 llvm-objdump: Handle BSS sections larger than the object file
The size of the uninitialized sections, like BSS, can exceed the size of
the object file.

Do not attempt to grab the contents of such sections.

5b003bb869 llvm-readobj: fix MachO relocatoin printing a bit.
There were two issues here:
1. At the very least, scattered relocations cannot use the same code to
   determine the corresponding symbol being referred to. For some reason we
   pretend there is no symbol, even when one actually exists in the symtab, so to
   match this behaviour getRelocationSymbol should simply return symbols_end for
   scattered relocations.
2. Printing "-" when we can't get a symbol (including the scattered case, but
   not exclusively), isn't that helpful. In both cases there *is* interesting
   information in that field, so we should print it. As hex will do.

aa6a13a8e2 Do not XFAIL test/tools/llvm-cov tests on powerpc64le
All tests in test/tools/llvm-cov fail on big-endian targets and are
supposed to be XFAILed there.  However, including "powerpc64" in the
XFAIL line is now incorrect, since that matches both powerpc64- and
powerpc64le- targets, and the tests pass on the latter.

Update the XFAIL lines to use powerpc64- instead (like mips64-).

6d81fc75c4 ProfileData: Allow multiple profiles in RawInstrProfReader
Allow multiple raw profiles to coexist in a single .profraw file,
given the following conditions:

- Zero padding at the end of or between profiles will be skipped.
- Each profile must start with a valid header.
- Mixing endianness or pointer sizes in concatenated profiles files is
  not allowed.

This is needed to handle cases where a program's shared libraries are
profiled as well as the main executable itself, as we'll need to emit
each executable's counters. Combining the tables in the runtime would
be expensive for the instrumented program.

c92330c18c llvm-cov: Handle missing source files as GCOV does
If the source files referenced by a gcno file are missing, gcov
outputs a coverage file where every line is simply /*EOF*/.  This also
occurs for lines in the coverage that are past the end of a file that
is found.

This change mimics gcov.

56d05e468c llvm-cov: Implement --no-output

688567e91c llvm-cov: Fix handling of line zero appearing in a line table
Reading line tables in llvm-cov was pretty broken, but would happen to
work as long as no line in the table was 0. It's not clear to me
whether a line of zero *should* show up in these tables, but deciding
to read a string in the middle of the line table is certainly the
wrong thing to do if it does.

I've also added some comments, as trying to figure out what this block
of code was doing was fairly unpleasant.

0695b20d9a InstrProf: Check pointer size in raw profile
Since the profile can come from 32-bit machines, we need to check the
pointer size.  Change the magic number to facilitate this.

Adds tests for reading 32-bit and 64-bit binaries (both big- and
little-endian).  The tests write a binary using printf in RUN lines
(like raw-magic-but-no-header.test).  Assuming the bots don't complain,
this seems like a better way forward for testing RawInstrProfReader than
committing binary files.

99995267ae Object/COFF: Support large relocation table.
NumberOfRelocations field in COFF section table is only 16-bit wide. If an
object has more than 65535 relocations, the number of relocations is stored
to VirtualAddress field in the first relocation field, and a special flag
(IMAGE_SCN_LNK_NRELOC_OVFL) is set to Characteristics field.

In test we cheated a bit. I made up a test file so that it has
IMAGE_SCN_LNK_NRELOC_OVFL flag but the number of relocations is much smaller
than 65535. This is to avoid checking in a large test file just to test a
file with many relocations.

abb1fadc79 Fix the printing of n_type.
Despite the name, n_type contains the type of the symbol, but also if it is
extern or private extern.

afee151fe8 llvm-objdump: Indent unwind info contents.
Unwind info contents were indented at the same level as function table
contents. That's a bit confusing because the unwind info is pointed by
function table. In other places we usually increment indentation depth
by one when dereferncing a pointer.

This patch also removes extraneous newlines between function tables.
