[PowerPC] Fix small argument stack slot offset for LE
When small arguments (structures < 8 bytes or "float") are passed in a
stack slot in the ppc64 SVR4 ABI, they must reside in the least
significant part of that slot. On BE, this means that an offset needs
to be added to the stack address of the parameter, but on LE, the least
significant part of the slot has the same address as the slot itself.
For the most part, this is handled in the LLVM back-end, where I just
fixed the LE case in commit r211368.
However, there is one piece of the clang front-end that is also aware of
these stack-slot offsets: PPC64_SVR4_ABIInfo::EmitVAArg. This patch
updates that routine to take endianness into account.

Command files that switch input handlers didn't work, now they do.
The issue was when we called Debugger::RunIOHandler(), it would run the current IOHandler by activating it, and running it and then try to pop it and exit regardless of wether it was on top or not.
The new code will push the IOHandler that was passed in, and run the IOHandlers until the one passed in is successfully popped. This allows files for the "command source" to switch input handlers:
% cat /tmp/commands
br s -S alignLeftEdges:
br command add
bt
frame var
po self
DONE
b s -n main
br command add
bt
frame var
DONE
Note above we set a breakpoint, then add commands do it. The "br command add" will push the breakpoint comment gatherer until it sees "DONE" and then pop itself off the stack. The a new breakpoint will be set and it does the same thing again.
Now this file can be sourced from the command line:

Frontend: Add a CC1 flag to dump module dependencies to a directory
This adds the -module-dependency-dir to clang -cc1, which specifies a
directory to copy all of a module's dependencies into in a form
suitable to be used as a VFS using -ivfsoverlay with the generated
vfs.yaml.
This is useful for crashdumps that involve modules, so that the module
dependencies will be intact when a crash report script is used to
reproduce a problem on another machine.
We currently encode the absolute path to the dump directory, due to
limitations in the VFS system. Until we can handle relative paths in
the VFS, users of the VFS map may need to run a simple search and
replace in the file.

Fix PR20069: bad loop pragma arguments crash FE
This patch fixes a crash when handling malformed arguments to loop pragmas such
as: "#pragma clang loop vectorize(()". Essentially any argument which is not an
identifier or constant resulted in a crash. This patch also changes a couple of
the error messages which weren't quite correct. New behavior with this patch vs
old behavior:
#pragma clang loop vectorize(1)
OLD: error: missing keyword; expected 'enable' or 'disable'
NEW: error: invalid argument; expected 'enable' or 'disable'
#pragma clang loop vectorize()
OLD: error: expected ')'
NEW: error: missing argument to loop pragma 'vectorize'

Switch over to using object_getClass to get the class of an object. Previously we were

Fixed up gdb-remote auxv regex issues with binary data.
Fixes two causes for https://github.com/tfiala/lldb/issues/7.
1. Ensures the inferior program has started executing, by printing
a message on output first thing (per the "message:" command line arg)
and waiting for that text to arrive before doing any checks related
to auxv support.
2. Fixes up auxv-related regex patterns to be compiled with the Python
re.MULTILINE and re.DOTALL options. The multiline is needed because
the binary data can include what look like newlines when interpreted
as text, and the DOTALL is needed to have the (.*) content portion match
newlines.
Added interrupt packet helper methods to add interrupt test sequence
packets and parse the results from them.

[ValueTracking] Extend range metadata to call/invoke
Summary:
With this patch, range metadata can be added to call/invoke including
IntrinsicInst. Previously, it could only be added to load.
Rename computeKnownBitsLoad to computeKnownBitsFromRangeMetadata because
range metadata is not only used by load.
Update the language reference to reflect this change.
Test Plan:
Add several tests in range-2.ll to confirm the verifier is happy with
having range metadata on call/invoke.
Add two tests in AddOverFlow.ll to confirm annotating range metadata to
call/invoke can benefit InstCombine.

Emit DWARF3 call frame information when DWARF3+ debug info is requested
Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting
DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the
newer CIE version when we are emitting DWARF 3 or 4. This will not reduce
compatibility, as we already emit other DWARF3/4 features, and is worth doing as
the DWARF3 spec removed some ambiguities in the interpretation of call frame
information.
It also fixes a minor bug where the "return address" field of the CIE was
encoded as a ULEB128, which is only valid when the CIE version is 3. There are
no test changes for this, because (as far as I can tell) none of the platforms
that we test have a return address register with a DWARF register number >127.
