[PowerPC] Handle base load with reservation mnemonic
The Power ISA defined l[bhwdq]arx as both base and
extended mnemonics. The base mnemonic takes the EH
bit as an operand and the extended mnemonic omits
it, making it implicitly zero. The existing
implementation only handles the base mnemonic when
EH is 1 and internally produces a different
instruction. There are historical reasons for this.
This patch simply removes the limitation introduced
by this implementation that disallows the base
mnemonic with EH = 0 in the ASM parser.
This resolves an issue that prevented some files
in the Linux kernel from being built with
-fintegrated-as.
Also fix a crash if the value is not an integer immediate.

[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.

[PowerPC] Support @tls in the asm parser
This adds support for the last missing construct to parse TLS-related
assembler code:
add 3, 4, symbol@tls
The ADD8TLS currently hard-codes the @tls into the assembler string.
This cannot be handled by the asm parser, since @tls is parsed as
a symbol variant. This patch changes ADD8TLS to have the @tls suffix
printed as symbol variant on output too, which allows us to remove
the isCodeGenOnly marker from ADD8TLS. This in turn means that we
can add a AsmOperand to accept @tls marked symbols on input.
As a side effect, this means that the fixup_ppc_tlsreg fixup type
is no longer necessary and can be merged into fixup_ppc_nofixup.

[PowerPC] Accept 17-bit signed immediates for addis
The assembler currently strictly verifies that immediates for
s16imm operands are in range (-32768 ... 32767). This matches
the behaviour of the GNU assembler, with one exception: gas
allows, as a special case, operands in an extended range
(-65536 .. 65535) for the addis instruction only (and its
extended mnemonic lis).
The main reason for this seems to be to allow using unsigned
16-bit operands for lis, e.g. like lis %r1, 0xfedc.
Since this has been supported by gas for a long time, and
assembler source code seen "in the wild" actually exploits
this feature, this patch adds equivalent support to LLVM
for compatibility reasons.

[PowerPC] Add assembler parser
This adds assembler parser support to the PowerPC back end.
The parser will run for any powerpc-*-* and powerpc64-*-* triples,
but was tested only on 64-bit Linux. The supported syntax is
intended to be compatible with the GNU assembler.
The parser does not yet support all PowerPC instructions, but
it does support anything that is generated by LLVM itself.
There is no support for testing restricted instruction sets yet,
i.e. the parser will always accept any instructions it knows,
no matter what feature flags are given.
Instruction operands will be checked for validity and errors
generated. (Error handling in general could still be improved.)
The patch adds a number of test cases to verify instruction
and operand encodings. The tests currently cover all instructions
from the following PowerPC ISA v2.06 Book I facilities:
Branch, Fixed-point, Floating-Point, and Vector.
Note that a number of these instructions are not yet supported
by the back end; they are marked with FIXME.
A number of follow-on check-ins will add extra features. When
they are all included, LLVM passes all tests (including bootstrap)
when using clang -cc1as as the system assembler.
