76ecc3d35b Thumb2 parsing and encoding for LDMIA. 
Choose 32-bit vs. 16-bit encoding when there's no .w suffix in post-processing
as match classes are insufficient to handle the context-sensitiveness of
the writeback operand's legality for the 16-bit encodings.

5ffedb9352 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

9ab0f25fc1 invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.

5fbe5e783e Some autoconf tests use module level inline asm to test compiler's handling of 
.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

47a0d52b69 ARM thumb assembly parsing for arithmetic flag setting instructions. 
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

7ce057983e ARM refactoring assembly parsing of memory address operands. 
Memory operand parsing is a bit haphazzard at the moment, in no small part
due to the even more haphazzard representations of memory operands in the .td
files. Start cleaning that all up, at least a bit.

The addressing modes in the .td files will be being simplified to not be
so monolithic, especially with regards to immediate vs. register offsets
and post-indexed addressing. addrmode3 is on its way with this patch, for
example.

This patch is foundational to enable going back to smaller incremental patches
for the individual memory referencing instructions themselves. It does just
enough to get the basics in place and handle the "make check" regression tests
we already have.

Follow-up work will be fleshing out the details and adding more robust test
cases for the individual instructions, starting with ARM mode and moving from
there into Thumb and Thumb2.

Fill in the missing fixed bits and the register operand bits of the instruction
encoding. Refactor the definition to make the mode explicit, which is
consistent with how loads and stores are normally represented and makes
parsing much easier. Add parsing aliases for pseudo-instruction variants.
Update the disassembler for the new representations. Add tests for parsing and
encoding.

cf121c35c4 ARM assembly parsing and encoding for BLX (immediate). 
Add parsing support for BLX (immediate). Since the register operand version is
predicated and the label operand version is not, we have to use some special
handling to get the operand list right for matching.

c37d4bbf1f Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates. 
llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.

f2a35fbd60 Move some ELF directives into ELF asm parser. 
The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.

10c7d70a4e ARM assembly parsing POP/PUSH mnemonics. 
Aliases for LDM/STM. The single-register versions should encode to LDR/STR
with writeback, but we don't (yet) get that correct. Neither does Darwin's
system assembler, though, so that's not a deal-breaker of a limitation.

59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo 
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

6b8f1e35ea ARM Assembly support for Thumb mov-immediate. 
Correctly parse the forms of the Thumb mov-immediate instruction:
  1. 8-bit immediate 0-255.
  2. 12-bit shifted-immediate.

The 16-bit immediate "movw" form is also legal with just a "mov" mnemonic,
but is not yet supported. More parser logic necessary there due to fixups.

861b9c6a39 This fixes one divergence between LLVM and binutils for ARM in the 
text section.

Assume the following bit of annotated assembly:

.section	.data.rel.ro,"aw",%progbits
.align	2
.LAlpha:
.long	startval(GOTOFF)

.text
.align	2
.type	main,%function
.align	4

main: ;;; assume "main" starts at offset 0x20
0x0	push	{r11, lr}
0x4	movw	r0, :lower16:(.LAlpha-(.LBeta+8))
;;; ==> (.AddrOf(.LAlpha) - ((.AddrOf(.LBeta) - .AddrOf(".")) + 8)
;;; ==> (??? - ((16-4) + 8) = -20
0x8	movt	r0, :upper16:(.LAlpha-(.LBeta+8))
;;; ==> (.AddrOf(.LAlpha) - ((.AddrOf(.LBeta) - .AddrOf(".")) + 8)
;;; ==> (??? - ((16-8) + 8) = -16
0xc	... blah

.LBeta:
0x10	add	r0, pc, r0
0x14	... blah

.LGamma:
0x18	add	r1, pc, r1

Above snippet results in the following relocs in the .o file for the
first pair of movw/movt instructions

00000024 R_ARM_MOVW_PREL_NC .LAlpha
00000028 R_ARM_MOVT_PREL .LAlpha

And the encoded instructions in the .o file for main: must be

00000020 <main>:
20:	e92d4800 push	{fp, lr}
24:	e30f0fec movw	r0, #65516	; 0xffec i.e. -20
28:	e34f0ff0 movt	r0, #65520	; 0xfff0 i.e. -16

However, llc (prior to this commit) generates the following sequence

00000020 <main>:
20:	e92d4800 push	{fp, lr}
24:	e30f0fec movw	r0, #65516	; 0xffec - i.e. -20
28:	e34f0fff movt	r0, #65535	; 0xffff - i.e. -1

What has to happen in the ArmAsmBackend is that if the relocation is PC
relative, the 16 bits encoded as part of movw and movt must be both addends,
not addresses. It makes sense to encode addresses by right shifting the value
by 16, but the result is incorrect for PIC.
i.e., the right shift by 16 for movt is ONLY valid for the NON-PCRel case.

This change agrees with what GNU as does, and makes the PIC code run.

MC/ARM/elf-movt.s covers this case.

all the instruction have:

    let Inst{31-27} = 0b1110; // non-predicated

Before, the ARM decoder was confusing:

> 0x40 0xf3 0xb8 0x80

as:

Opcode=16 Name=ADCSSrs Format=ARM_FORMAT_DPSOREGFRM(5)
 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0

-------------------------------------------------------------------------------------------------

	adcs	pc, r8, r0, asr #6

since the cond field for ADCSSrs is a wild card, and so is ADCrs, with the ADCSSrs having Inst{20} as '1'.

Now, the AR decoder behaves correctly:

40829ed6f5 - Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and 
{STR,LDC}{2}_PRE.
- Fixed the encoding in some places.
- Some of those instructions were using am2offset and now use addrmode2.
Codegen isn't affected, instructions which use SelectAddrMode2Offset were not
touched.
- Teach printAddrMode2Operand to check by the addressing mode which index
mode to print.
- This is a work in progress, more work to come. The idea is to change places
which use am2offset to use addrmode2 instead, as to unify assembly parser.
- Add testcases for assembly parser
