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.

Summary:
Authored by Florian Zeitz.
This implements the missing stacksave/stackrestore intrinsics via expansion.
Output of `llc -O0 -march=avr ~/devel/llvm/test/CodeGen/Generic/stacksave-restore.ll` for sanity checking (comments mine):

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.

This allows the use of the 'read_register' intrinsics used by clang's
named register globals features.
