c6df9883da Have the X86 back-end emit the alias instead of what's being aliased. In most 
cases, it's much nicer and more informative reading the alias.

857b1939da Fix the instruction table entries for AI1_adde_sube_s_irs multiclass definition so that 
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

e6d69e7dbe ADR was added with the wrong encoding for inst{24-21}, and the ARM decoder was fooled. 
Set the encoding bits to {0,?,?,0}, not 0.  Plus delegate the disassembly of ADR to
the more generic ADDri/SUBri instructions, and add a test case for that.

o A8.6.195 STR (register) -- Encoding T1
o A8.6.193 STR (immediate, Thumb) -- Encoding T1

It has been changed so that now they use different addressing modes
and thus different MC representation (Operand Infos).  Modify the
disassembler to reflect the change, and add relevant tests.

276f6f9cf9 There were two issues fixed: 
1. The ARM Darwin *r9 call instructions were pseudo-ized recently.
   Modify the ARMDisassemblerCore.cpp file to accomodate the change.

2. The disassembler was unnecessarily adding 8 to the sign-extended imm24:

   imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate)
                                       // Encoding A1

   It has no business doing such.  Removed the offending logic.

Add test cases to arm-tests.txt.

handled, which led to difficulties when operand match classes were
more complicated than simple subclass relationships.

953a2a3dee Teach ARM/MC/ELF about gcc compatible reloc output to get past odd linkage 
failures with relocations.

The code committed is a first cut at compatibility for emitted relocations in
ELF .o.

Why do this? because existing ARM tools like emitting relocs symbols as
explicit relocations, not as section-offset relocs.

Result is that with these changes,
1) relocs are now substantially identical what to gcc outputs.
2) larger apps (including many spec2k tests) compile, cross-link, and pass

Added reminder fixme to tests for future conversion to .s form.

6cd0b17ba7 When matching asm operands, always try to match the most restricted type first. 
Unfortunately, while this is the "right" thing to do, it breaks some ARM
asm parsing tests because MemMode5 and ThumbMemModeReg are ambiguous.  This
is tricky to resolve since neither is a subset of the other.

XFAIL the test for now.  The old way was broken in other ways, just ways
we didn't happen to be testing, and our ARM asm parsing is going to require
significant revisiting at a later point anyways.

2bf6afc277 Relax alignment fragments. 
With this we don't need the EffectiveSize field anymore. Without that field
LayoutFragment only updates offsets and we don't need to invalidate the
current fragment when it is relaxed (only the ones following it).

This is also a very small improvement in the accuracy of the layout info as
we now use the after relaxation size immediately.
