7ca2a7d742 [PowerPC] Add support for dcbtst and icbt (prefetch)
Adds code generation support for dcbtst (data cache prefetch for write) and
icbt (instruction cache prefetch for read - Book E cores only).

We still end up with a 'cannot select' error for the non-supported prefetch
intrinsic forms. This will be fixed in a later commit.

Fixes PR20692.

47eac58333 [PowerPC] Generate little-endian object files
As a first step towards real little-endian code generation, this patch
changes the PowerPC MC layer to actually generate little-endian object
files.  This involves passing the little-endian flag through the various
layers, including down to createELFObjectWriter so we actually get basic
little-endian ELF objects, emitting instructions in little-endian order,
and handling fixups and relocations as appropriate for little-endian.

The bulk of the patch is to update most test cases in test/MC/PowerPC
to verify both big- and little-endian encodings.  (The only test cases
*not* updated are those that create actual big-endian ABI code, like
the TLS tests.)

Note that while the object files are now little-endian, the generated
code itself is not yet updated, in particular, it still does not adhere
to the ELFv2 ABI.

19d2b78978 [PowerPC] Support time base instructions
This adds support for the old-style time base instructions;
while new programs are supposed to use mfspr, the mftb instructions
are still supported and in use by existing assembler files.

3bd2b92267 [PowerPC] Also add "msync" alias
This adds an alias for "msync" (which is used on Book E
systems instead of "sync").

4c1d023de8 [PowerPC] Add some existing instructions to ppc64-encoding-bookII.s
The test case had a couple of FIXMEs where the instruction is in
fact already supported by the back-end.  In some other case, while
the generic form of the instruction is not yet supported, a
specialized form is.  This adds tests for those already supported
instructions / instruction forms.

and provides aliases for "lwsync" and "ptesync".

8e4ba8f7b1 [PowerPC] Add some Book II instructions to AsmParser
This patch adds a couple of Book II instructions (isync, icbi) to the
PowerPC assembler parser.  These are needed when bootstrapping clang
with the integrated assembler forced on, because they are used in
inline asm statements in the code base.

The test case adds the full list of Book II storage control instructions,
including associated extended mnemonics.  Again, those that are not yet
supported as marked as FIXME.
