Yaron Keren 4988786b0f Enable five passing dsymutil tests on Windows.
These tests pass with Windows 7 x64 + MSYS2. I'll see if the bots like
them as well and disable the failing ones.

Frederic Riss 0948db6064 [dsymutil] Add (unimplemented) --flat option
dsymutil should by default generate dSYM bundles which are filesystem
hierarchies containing the debug info and an additional Info.plist.
Currently llvm-dsymutil emits raw binaries containing the debug info.
This is what we call the 'flat mode'. Add a -f/-flat option that is
supposed to enable that flat mode, but don't wire it for now, only
pass it to the tests that will need it to stay functional once we
do bundle generation by default.
This basically makes this commit NFC and removes the noise from the
actual commit that adds support for bundle generation.

Frederic Riss 10e728a48c [dsymutil] Temporarily disable some tests on windows.
It seems one windows bot fails since I added ilne table linking to
llvm-dsymutil (see r232333 commit thread).
Disable the affected tests until I can figure out what's happening.

Frederic Riss bce93ff011 [dsymutil] Add support to generate .debug_pubnames and .debug_pubtypes
The information gathering part of the patch stores a bit more information
than what is strictly necessary for these 2 sections. The rest will
become useful when we start emitting __apple_* type accelerator tables.

Frederic Riss 63786b016f [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.

Frederic Riss dfb9790a3d [dsymutil] Add support for debug_loc section.
There is no need to look into the location expressions to transfer them,
the only modification to apply is to patch their base address to reflect
the linked function address.

Frederic Riss 563b1b057a [dsymutil] Generate debug_aranges section.
This actually shares most of its implementation with the  generation
of the debug_ranges (the absence of 'a' is not a typo) contribution
for the unit's DW_AT_ranges attribute.

Frederic Riss 25440876b0 [dsymutil] Implement DW_AT_ranges linking.
Nothing fancy, just a straightforward offset to apply to the original
debug_ranges entries to get them in line with the linked addresses.

Frederic Riss 6afcfce2d9 [dsymutil] Fix handling of cross-cu forward references.
We recorded the forward references in the CU that holds the referenced
DIE, but this is wrong as those will get resoled *after* the CU that
holds the reference. Record the references in their originating CU along
with a pointer to the remote CU to be able to compute the fixed up
offset at the right time.

Frederic Riss 5a62dc3793 [dsymutil] Add relocation of compile_units low_pc/high_pc.
They need to be handled specifically as they could vary pretty
widely depending on how the linker moves functions around.

Frederic Riss 111a0a8305 [dsymutil] Fix location cloning for newer dwarf versions.
The typo got unnoticed because we were testing only on Dwarf 2. Add a
Dwarf4 test that exercises the code path, and also tests some newer
FORMs that the other test doesn't cover.
