28b8dea315 For llvm-objdump, with the -archive-headers and -macho options, use the -non-verbose
option to print the archive headers using raw numeric values.  Also add the -archive-member-offsets
for use with these to also trigger printing of the offset of the archive member from the start
of the archive.

b9e97c799e llvm-cov: Require a subcommand when invoked as llvm-cov
A while ago llvm-cov gained support for clang's instrumentation based
profiling in addition to its gcov support, and subcommands were added
to choose which behaviour to use. When no subcommand was specified, we
fell back to gcov compatibility with a warning that a subcommand would
be required in the future. Now, we require the subcommand.

Note that if the basename of llvm-cov is gcov (via symlink or
hardlink, for example), we still use the gcov compatible behaviour
with no subcommand required.

bd59e21808 InstrProf: Remove xfails for big-endian from coverage tests
This still doesn't actually work correctly for big endian input files,
but since these tests all use little endian input files they don't
actually fail. I'll be committing a real fix for big endian soon, but
I don't have proper tests for it yet.

5e4931b489 InstrProf: Do a better job of reading coverage mapping data.
This code was casting regions of a memory buffer to a couple of
different structs. This is wrong in a few ways:

1. It breaks aliasing rules.
2. If the buffer isn't aligned, it hits undefined behaviour.
3. It completely ignores endianness differences.
4. The structs being defined for this aren't specifying their padding
   properly, so this doesn't even represent the data properly on some
   platforms.

This commit is mostly NFC, except that it fixes reading coverage for
32 bit binaries as a side effect of getting rid of the mispadded
structs. I've included a test for that.

I've also baked in that we only handle little endian more explicitly,
since that was true in practice already. I'll fix this to handle
endianness properly in a followup commit.

e6412a691d [dsymutil] Add support for linking line tables.
This code comes with a lot of cruft that is meant to mimic darwin's
dsymutil behavior. A much simpler approach (described in the numerous
FIXMEs that I put in there) gives the right output for the vast
majority of cases. The extra corner cases that are handled differently
need to be investigated: they seem to correctly handle debug info that
is in the input, but that info looks suspicious in the first place.

Anyway, the current code needs to handle this, but I plan to revisit it
as soon as the big round of validation against the classic dsymutil is
over.

e7a356409d [dsymutil] Add function size to the debug map.
The debug map embedded by ld64 in binaries conatins function sizes.
These sizes are less precise than the ones given by the debug information
(byte granularity vs linker atom granularity), but they might cover code
that is referenced in the line table but not in the DIE tree (that might
very well be a compiler bug that I need to investigate later).
Anyway, extracting that information is necessary to be able to mimic
dsymutil's behavior exactly.

21d3c12750 Make test added in r231902 actually be executed.
There were also errors in the CHECK line which I fixed and the test
doesn't actually pass as the "100" is in the wrong line. Not sure
whether this is a test failure or a coverage failure so making the test
XFAIL for now.

This format's easier to understand and update by hand.

3c8e619a71 [dsymutil] Apply relocations to DIE data before cloning.
Doing this gets function's low_pc and global variable's locations right
in the output debug info. It also could get right other attributes
that need to be relocated (in linker terms), but I don't know of any
other than the address attributes.

This doesn't fixup low_pc attributes in compile_unit, lexical_block
or inlined subroutine, nor does it get right high_pc attributes
for function. This will come in a subsequent commit.
