This patch implements assembly support for the 2022 A-Profile Architecture
extension FEAT_LRCPC3. FEAT_LRCPC3 is AArch64 only and introduces new
variants of load/store instructions with release consistency ordering.

Specs for individual instructions can be found here:
https://developer.arm.com/documentation/ddi0602/2022-09/Base-Instructions/

This feature is optionally available from v8.2a and therefore not enabled by
default.
