Juergen Ributzka f560928889 [RuntimeDyld][MachO][AArch64] Add a helper function for encoding addends in instructions.
Factor out the addend encoding into a helper function and simplify the
processRelocationRef.

Also add a few simple rtdyld tests. More tests to come once GOTs can be tested too.

Lang Hames 87c025bb17 [RuntimeDyld] Replace a crufty old ARM RuntimeDyld test with a new one that uses
RuntimeDyldChecker.

This allows us to remove one of the six remaining object files in the LLVM
source tree.

Chandler Carruth d5821f36d9 Fix this test to not write to the source tree, and instead to write to
a temporary file. This fixes the test in cases where the source tree is
mounted read-only.

Lang Hames 116d1354b6 [RuntimeDyld] Make sure that RuntimeDyld regression tests only run for targets
that have been enabled.

Without this, testers will fail when llvm-rtdyld is invoked with triples for
unsupported targets.

Lang Hames e1c1138a38 [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.
This patch adds a "-verify" mode to the llvm-rtdyld utility. In verify mode,
llvm-rtdyld will test supplied expressions against the linked program images
that it creates in memory. This scheme can be used to verify the correctness
of the relocation logic applied by RuntimeDyld.

The expressions to test will be read out of files passed via the -check option
(there may be more than one of these). Expressions to check are extracted from
lines of the form:
# rtdyld-check: <expression>

This system is designed to fit the llvm-lit regression test workflow. It is
format and target agnostic, and supports verification of images linked for
remote targets. The expression language is defined in
llvm/include/llvm/RuntimeDyldChecker.h . Examples can be found in
test/ExecutionEngine/RuntimeDyld.

Lang Hames 9f7d14756d Fix testers by removing dubious testcase for r209154.
It turns out that not all the world is x86-64. Who knew?

I'll get to work on a more appropriate test case for this patch.

Lang Hames 1fcbc08500 [RuntimeDyld] Fix x86-64 MachO GOT relocation handling.
For GOT relocations the addend should modify the offset to the
GOT entry, not the value of the entry itself. Teach RuntimeDyldMachO
to do The Right Thing here.

Fixes <rdar://problem/16961886>.

Daniel Dunbar 9efbedfd35 [tests] Cleanup initialization of test suffixes.
- Instead of setting the suffixes in a bunch of places, just set one master
   list in the top-level config. We now only modify the suffix list in a few
   suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py).

 - Aside from removing the need for a bunch of lit.local.cfg files, this enables
   4 tests that were inadvertently being skipped (one in
   Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and
   CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been
   XFAILED).

 - This commit also fixes a bunch of config files to use config.root instead of
   older copy-pasted code.

Lang Hames fe2833be4d Optimistically ignore scattered relocations in MachO in RuntimeDyld. This
un-breaks simple use cases while I work on more general support.
