Luís Marques 3e3d432461 [RISCV] Split the pseudo instruction splitting pass
Extracts the atomic pseudo-instructions' splitting from `riscv-expand-pseudo`
/ `RISCVExpandPseudo` into its own pass, `riscv-expand-atomic-pseudo` /
`RISCVExpandAtomicPseudo`. This allows for the expansion of atomic operations
to continue to happen late (the new pass is added in `addPreEmitPass2`, so
those expansions continue to happen in the same place), while the remaining
pseudo-instructions can now be expanded earlier and benefit from more
optimization passes. The nonatomics pass is now added in `addPreSched2`.
