RISC-V: Add basic support for the Zacas extension
This patch adds support for amocas.{b|h|w|d}. Support for amocas.q
(64/128 bit cas for rv32/64) will be added in a future patch.
Extension: https://github.com/riscv/riscv-zacas
Ratification: https://jira.riscv.org/browse/RVS-680
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc: Add zacas extension.
* config/riscv/arch-canonicalize: Make zacas imply zaamo.
* config/riscv/riscv.opt: Add zacas.
* config/riscv/sync.md (zacas_atomic_cas_value<mode>): New pattern.
(atomic_compare_and_swap<mode>): Use new pattern for compare-and-swap ops.
(zalrsc_atomic_cas_value_strong<mode>): Rename atomic_cas_value_strong.
* doc/sourcebuild.texi: Add Zacas documentation.
