e5cbaf140b Switch to using the LLVM CommandLine library so that our help
message is properly contaminated with nonsense about timing passes
that doesn't apply at all to this utility. :)

82bd5eaa71 Centralize the logic to permanently unify two instructions and make sure
it establishes a context and does a complaining diff.  Also make sure we
unify the prelude and postlude of a diff after a block-diff call.

02e116cb06 When unifying instructions during a block diff, actually complain about
any differences we see.  This should only happen if there are "non-structural"
differences between the instructions, i.e. differences which wouldn't cause
diff to return true.

dfb44ac690 Somehow I was getting reasonable results for the test cases I was interested
in despite not ever incrementing any path costs, so that the only nonzero costs
arose from the all-left path in the first column.  Anyway.  Perform the diff
starting from the beginning of the block to avoid capturing (say) loads of
allocas.

Vastly improves diff results on code that hasn't been mem2reg'ed.

3dd706b528 Add the llvm-diff tool, which performs a relatively naive structural
diff of a function.  There's a lot of cruft in the current version, and
it's pretty far from perfect, but it's usable.

Currently only capable of comparing functions.  Currently ignores metadata.
Currently ignores most attributes of functions and instructions.

Patches welcome.

84ae206c97 Clone and restore the module being reduced in
ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).

Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.

c510a7097b there is now no reason to link in TARGETS_TO_BUILD since we list
arm explicitly.  X86 and ARM are the only two targets that support
disassembly, so our explicit list is enough.  These other targets
weren't getting pulled in anyway though, since there were no 
references to their symbols.

847da55716 start straightening out libedis's dependencies and make it fit
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes. 

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

5e721d7682 Implement the "linker_private_weak" linkage type. This will be used for
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.
