with the newer, cleaner model. It uses the IAPrinter class to hold the
information that is needed to match an instruction with its alias. This also
takes into account the available features of the platform.
There is one bit of ugliness. The way the logic determines if a pattern is
unique is O(N**2), which is gross. But in reality, the number of items it's
checking against isn't large. So while it's N**2, it shouldn't be a massive time
sink.

- Also emit a list of packages and groups sorted by name
- Avoid iterating over DenseSet so that the output of the arrays is deterministic.

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.

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.

attributes. These are requires for the new 'availability' attribute.

and geneate better functions in the long run.

This is a helper class that will make it easier to say which InstAliases can be
printed and which cannot (because of ambiguity).

On Win32 console, emitting char to col#79 causes linefeed, and the cursor will not return to col#79 upper line with backspace.

and for the YMM registers accessible on AVX-enabled
architectures. Instruction table support that enables AVX
instructions for the disassembler is in an upcoming patch.

CodeGenRegister entries. Use this information to more intelligently build
the literal register entires in the DAGISel matcher table. Specifically,
use a single-byte OPC_EmitRegister entry for registers with a value of
less than 256 and OPC_EmitRegister2 entry for registers with a larger value.
