[MIPS] Add load-link, store-conditional paired instructions
Add several baseline MIPS32R6[1] and MIPS64R6[2] instructions
that were omitted from the initial spec. These instructions
are optional in implementations but not associated with any
ASE or pseudo-ASE. Their presence is indicated by the XNP bit
in the Config5 register.
