Momchil Velikov 6c9066fe2e Recommit "[AArch64] Fix incorrect isLegalAddressingMode" ...

This patch recommits 0827e2fa3f after
reverting it in ed7ada259f.  Added
workround for `Targetlowering::AddrMode` no longer being an aggregate
in C++20.

`AArch64TargetLowering::isLegalAddressingMode` has a number of
defects, including accepting an addressing mode, which consists of
only an immediate operand, or not checking the offset range for an
addressing mode in the form `1*ScaledReg + Offs`.

This patch fixes the above issues.
