These used to be referenced by the CGI->AWI map (in AsmWriterEmitter), but
stored in a vector local to EmitPrintInstruction. Move the vector to
AsmWriterEmitter too.

and enables the instruction printer to print aliased
instructions.
Due to usage of RegisterOperands a change in common
code (utils/TableGen/AsmWriterEmitter.cpp) is required
to get the correct register value if it is a RegisterOperand.

When processing possible aliases, TableGen assumes that if an operand *can* be
an immediate, then it always *will* be. This is incorrect for the AArch64
backend. This patch inserts a check in the generated code to make sure isImm is
true first.

Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>.
That will happen in a future patch.
There are also two dyn_cast_or_null<>'s slipped in instead of
dyn_cast<>'s, since they were causing crashes with just dyn_cast<>.

48-bit if necessary, in order to reduce the generated code size.
We have 900 cases not covered by OpcodeInfo in ATT AsmWriter and more in Intel
AsmWriter and ARM AsmWriter.
This patch reduced the clang Release build size by 50k, running on a Mac Pro.

The TableGenBackend base class doesn't do much, and will be removed
completely soon.

We cannot limit the concatenated instruction names to 64K. ARM is
already at 32K, and it is easy to imagine a target with more
instructions.

This patch limited the concatenated register names to 64K which meant
that the total number of registers was many times less than 64K.
If any compilers actually enforce the 64K limit on string literals, and
it turns out to be a problem, we should fix that problem by not using
long string literals.

Original commit message:
Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect all 16-bit string table offsets. Also make sure the string to offset table string is not larger than 65536 characters since larger string literals aren't portable.

When TableGen starts creating its own register classes, the synthesized
classes won't have a Record reference. All register classes must have a
name, though.

TableGen had diagnostic printers sprinkled about in a few places. Pull them
together into a single location in Error.cpp.

Make the Elements vector private and expose an ArrayRef through
getOrder() instead. getOrder will eventually provide multiple
user-specified allocation orders.
Use the sorted member set for member and subclass tests. Clean up a lot
of ad hoc searches.

operands to an instruction aren't great, so an iterative search is fairly quick
and doesn't have the overhead of std::map.
