Summary:
le64 is a generic little-endian 64-bit processor, mimicking le32.

Apparently, PEEKUSER/POKEUSER is something x86 specific, so I had to rework it for AArch64. This fixes assertion that occurs whenever lldb started on AArch64 device tried to read PC register (or any other register)
See http://reviews.llvm.org/D5232 for more details.

Vector MUL/MLAs have tied operands, which gives us extra constraints
that we currently can't handle. Instead of silently doing the wrong
thing, remove support to be readded later properly.
llvm-svn: 217690
Defs are seen before uses, so a def without the kill flag doesn't necessarily
mean that the register is not killed on that instruction. It may be killed
in a later use operand.

As far as I can tell UTF-8 has been supported since the beginning of Python's
codec support, and it's the de facto standard for text these days, at least
for primarily-English text. This allows us to put Unicode into lit RUN lines.

Cross-class copies being expensive is actually a trait of the microarchitecture, but as I haven't yet seen an example of a microarchitecture where they're cheap it seems best to just enable this by default, covering the non-mcpu build case.

It turned out that we have to bridge more stuff between the executable
and the ASan RTL DLL than just __asan_option_detect_stack_use_after_return.
See PR20918 for more details.

We now verify that such functions are correctly detected even in combination
with delinearization. This change is added to ensure we have good test coverage
for the subsequent delinearization fix.
We also remove unnecessary instructions from the test case.

Summary:
Each check can implement readOptions and storeOptions methods to read
and store custom options. Each check's options are stored in a local namespace
to avoid name collisions and provide some sort of context to the user.

Deleted virtual functions get _purecall inserted into the vftable.
Earlier CTPs would simply stick nullptr in there.
N.B. MSVC can't handle deleted virtual functions which require return
adjusting thunks, they give an error that a deleted function couldn't be
called inside of a compiler generated function. We get this correct by
making the thunk have a __purecall entry as well.

ProcessStructReader instead of reading the structure out of libdispatch
by hand. I will convert more of the struct readers in SystemRuntimeMacOSX
over to use this class eventually.

* Sends a SIGSTOP to the process.
* Fixes busted SIGSTOP handling. Now builds a list of non-stopped
that we wait for the PTRACE group-stop for. When the final must-stop
tid gets its group stop, we propagate the process state change.
Only the signal receiving the notification of the pending SIGSTOP
is marked with the SIGSTOP signal. All the rest, if they weren't
already stopped, are marked as stopped with signal 0.
* Fixes a few broken tests.
* Marks the Linux test I added earlier as expect-pass (no longer XFAIL).
Implements fix for http://llvm.org/bugs/show_bug.cgi?id=20908.

This fixes a call to sys::fs::equivalent that should've been to
CodeCoverageTool::equivalentFiles, which lets us restore the test of
r217476 that was removed in r217478.
This reverts r217478, but the test works this time.
