all LDR/STR changes and left them to a future patch. Passing all
checks now.
- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and
fix the encoding wherever is possible.
- Add a new encoding bit to describe the index mode used and teach
printAddrMode2Operand to check by the addressing mode which index
mode to print.
- Testcases

- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT and
{STR,LDC}{2}_{PRE,POST} fixing the encoding wherever is possible.
- Move all instructions which use am2offset without a pattern to use
addrmode2.
- Add a new encoding bit to describe the index mode used and teach
printAddrMode2Operand to check by the addressing mode which index
mode to print.
- Testcases

{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

The STC_OPTION and STC2_OPTION instructions should have their coprocessor option enclosed in {}.

the change to ("tLDMIA", "tLDMIA_UPD"). Update the conflict resolution code and add
test cases for that.

According to A8.6.189 STM/STMIA/STMEA (Encoding T1), there's only tSTMIA_UPD available.
Ignore tSTMIA for the decoder emitter and add a test case for that.

These instructions were changed to not embed the addressing mode within the MC instructions
We also need to update the corresponding assert stmt. Also add a test case.

These two are test cases which should result in 'invalid instruction encoding' from running llvm-mc -disassemble.

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.

These instructions were changed to not embed the addressing mode within the MC instructions
We also need to update the corresponding assert stmt. Also add two test cases.

were incomplete. The assert stmt needs to be updated and the operand index incrment is wrong.
Fix the bad logic and add some sanity checking to detect bad instruction encoding;
and add a test case.

VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the
MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD
are two instructions. Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm()
to reflect the change.
Also add a test case.

gun as does. This makes it a lot easier to compare the output of both
as the addresses are now a lot closer.
