27d17d1713 Rename AttributeSet to AttributeList
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.

ab195580bf [WebAssembly] Don't old negative load/store offsets in fast-isel.
WebAssembly's load/store offsets are unsigned and don't wrap, so it's not
valid to fold in a negative offset.

bc87b9fd38 IR: Change the gep_type_iterator API to avoid always exposing the "current" type.
Instead, expose whether the current type is an array or a struct, if an array
what the upper bound is, and if a struct the struct type itself. This is
in preparation for a later change which will make PointerType derive from
Type rather than SequentialType.

6a5c3acce4 [WebAssembly] Reorder load/store operands to match binary encoding.
The p2align operand of a load/store is encoded before the offset
operand; reorder the MachineInstr operands accordingly.

a62715a542 [WebAssembly] Add an option to make get_local/set_local explicit.
This patch adds a pass, controlled by an option and off by default for
now, for making implicit get_local/set_local explicit. This simplifies
emitting wasm with MC.

8f7a717a1c [WebAssembly] Fix for 0xc call_indirect changes
Summary:
Need to reorder the operands to have the callee as the last argument.
Adds a pseudo-instruction, and a pass to lower it into a real
call_indirect.

This is the first of two options for how to fix the problem.

d2e71c8b48 [WebAssembly] Check return value of getRegForValue in FastISel
Previously, FastISel for WebAssembly wasn't checking the return value of
`getRegForValue` in certain cases, which would generate instructions
referencing NoReg. This patch fixes this behavior.

4c52f7daa5 [WebAssembly] Initial SIMD128 support.
Kicks off the implementation of wasm SIMD128 support (spec:
https://github.com/stoklund/portable-simd/blob/master/portable-simd.md),
adding support for add, sub, mul for i8x16, i16x8, i32x4, and f32x4.

The spec is WIP, and might change in the near future.
