[AArch64] Add separate feature flag for weaker release consistent load insns
The weaker release consistency support of ARMv8.3-A is allowed as an optional
extension for ARMv8.2-A, so separate command line option and feature flag is
added: -march=armv8.2-a+rcpc turns LDAPR, LDAPRB, LDAPRH instructions on.
