r298178 capitalized the fields in `ArgListEntry`. All the official
targets were updated accordingly, but as an experimental target AVR
was missed.

Summary:
This class is a list of AttributeSetNodes corresponding the function
prototype of a call or function declaration. This class used to be
called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is
typically accessed by parameter and return value index, so
"AttributeList" seems like a more intuitive name.
Rename AttributeSetImpl to AttributeListImpl to follow suit.
It's useful to rename this class so that we can rename AttributeSetNode
to AttributeSet later. AttributeSet is the set of attributes that apply
to a single function, argument, or return value.

Users often call getArgumentList().size(), which is a linear way to get
the number of function arguments. arg_size(), on the other hand, is
constant time.
In general, the fact that arguments are stored in an iplist is an
implementation detail, so I've removed it from the Function interface
and moved all other users to the argument container APIs (arg_begin(),
arg_end(), args(), arg_size()).

It is sufficient to skip emission of these arguments as we have nothing
to actually pass through the function call.
The AVR-GCC reference has nothing to say about zero-sized arguments,
presumably because C/C++ doesn't support them. This means we don't have
to worry about ABI differences.

Rename from addOperand to just add, to match the other method that has been
added to MachineInstrBuilder for adding more than just 1 operand.
See https://reviews.llvm.org/D28057 for the whole discussion.

Summary:
This pass will be used to relax instructions which use out of bounds
memory accesses to equivalent operations that can work with the
addresses.
The pass currently implements relaxation for the STDWPtrQRr instruction.
Without this pass, an assertion error would be hit in the pseudo expansion pass.
In the future, we will need to add more instructions to this pass. We can do
that on a case-by-case basic.

There was a bug where we would hit an assertion if 'Q' was used as a
constraint.
I also removed hardcoded register names to prefer regexes so the tests
don't break when the register allocator changes.
llvm-svn: 289325
Summary: This gets rid of the hardcoded 'r0' that was used previously.

These should've been checking whether the immediate is a 6-bit unsigned
integer.
If the immediate was '63', this would cause an assertion error which
shouldn't have occurred.
llvm-svn: 289315
We could previously select an integer which would hit an assertion error
in pseudo expansion.
The new type will also generate the appropriate fixups if needed, which
wasn't done beforehand.

This patch updates a bunch of places where add_dependencies was being explicitly called to add dependencies on intrinsics_gen to instead use the DEPENDS named parameter. This cleanup is needed for a patch I'm working on to add a dependency debugging mode to the build system.
llvm-svn: 287206
Summary:
A lot of the pseudo instructions are required because LLVM assumes that
all integers of the same size as the pointer size are legal. This means
that it will not currently expand 16-bit instructions to their 8-bit
variants because it thinks 16-bit types are legal for the operations.
This also adds all of the CodeGen tests that required the pass to run.

As it stands, the OperandMatchResultTy is only included in the generated
header if there is custom operand parsing. However, almost all backends
make use of MatchOperand_Success and friends from OperandMatchResultTy for
e.g. parseRegister. This is a pain when starting an AsmParser for a new
backend that doesn't yet have custom operand parsing. Move the enum to
MCTargetAsmParser.h.
This patch is a prerequisite for D23563
