The A extension has been split into two parts: Zaamo and Zalrsc.
This patch adds basic support by making the A extension imply Zaamo and
Zalrsc.
Zaamo/Zalrsc spec: https://github.com/riscv/riscv-zaamo-zalrsc/tags
Ratification: https://jira.riscv.org/browse/RVS-1995
v2:
Rebased and updated some testcases that rely on the ISA string.
v3:
Regex-ify temp registers in added testcases.
Remove unintentional whitespace changes.
Add riscv_{a|ztso|zaamo|zalrsc} docs to sourcebuild.texi (and move
core-v bi
extension doc into appropriate section).
Edwin Lu (1):
RISC-V: Add basic Zaamo and Zalrsc support
Patrick O'Neill (2):
RISC-V: Add Zalrsc and Zaamo testsuite support
RISC-V: Add Zalrsc amo-op patterns

Committed with a fixup to patch 3/3 where I added a missing -mabi=lp64d
that gave rv32 targets trouble on precommit. Also fixed up the changelog
for patch 1/3. I resent the committed series for the archiver.
