[PowerPC] Add the LLVM triple for powerpcle [1/5]

Add a triple for powerpcle-*-*.

This is a little-endian encoding of the 32-bit PowerPC ABI, useful in certain niche situations:

1) A loader such as the FreeBSD loader which will be loading a little endian kernel. This is required for PowerPC64LE to load properly in pseries VMs.
Such a loader is implemented as a freestanding ELF32 LSB binary.

2) Userspace emulation of a 32-bit LE architecture such as x86 on 64-bit hosts such as PowerPC64LE with tools like box86 requires having a 32-bit LE toolchain and library set, as they operate by translating only the main binary and switching to native code when making library calls.

3) The Void Linux for PowerPC project is experimenting with running an entire powerpcle userland.

[AIX] Update data directives for AIX assembly

Summary:
The standard data emission directives (e.g. .short, .long) in the AIX assembler
have the unintended consequence of aligning their output to the natural byte
boundary. This cause problems because we aren't expecting behavior from the
Data*bitsDirectives, so the final alignment of data isn't correct in some cases
on AIX.

This patch updated the Data*bitsDirectives to use .vbyte pseudo-ops instead to emit the
data, since we will emit the .align directives as needed. We update the existing
testcases and add a test for emission of struct data.

[Target][XCOFF] Correctly halt when mixing AIX or XCOFF with ppc64le

The code to prevent using `PPCXCOFFMCAsmInfo` with little-endian targets
used an incorrect check. Also, there does not appear to be sufficient
earlier checking to prevent failing this check, so the check here is
upgraded to be a `report_fatal_error`.

`PPCAIXAsmPrinter` was also missing a check against use with
little-endian targets. This patch adds such a check in.

[MC][Target][XCOFF] Consolidate MCAsmInfo XCOFF defaults; NFC

The setting of `MCAsmInfo` properties for XCOFF got split between
`MCAsmInfoXCOFF` and `PPCXCOFFMCAsmInfo`. Except for the properties that
are dependent on the target information being passed via the
constructor, the properties being set in `PPCXCOFFMCAsmInfo` had no
fundamental reason for being treated as specific for XCOFF on PowerPC.
Indeed, the property that might be considered more specific to PowerPC,
`NeedsFunctionDescriptors`, was set in `MCAsmInfoXCOFF`.

XCOFF being specific to PowerPC anyway, this patch consolidates the
setting of the properties into `MCAsmInfoXCOFF` except for the cases
that are dependent on the information provided via the
`PPCXCOFFMCAsmInfo` constructor.

This patch also reorders the assignments to the fields to match the
declaration order in `MCAsmInfo`.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.

Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.
