Arthur Eubanks 1c7f32334d [TargetLowering] Only inspect attributes in the arguments for ArgListEntry 
Parameter attributes are considered part of the function [1], and like
mismatched calling conventions [2], we can't have the verifier check for
mismatched parameter attributes.

This is a reland after fixing MSan issues in D102667.

Tim Northover f9b560aa8e AArch64: get type from correct result when forming BFX 
Some nodes produce multiple values so when obtaining the type of an ISD::OR we
need to make sure we ask for the correct one. Hopefully that's all of them.

Chad Rosier be879ea751 [AArch64] Spot SBFX-compatible code expressed with sign_extend. 
This is very similar to r271677, but for extracts from i32 with the SIGN_EXTEND
acting on a arithmetic shift.
