Description

Fix and improve arm64 atomic operations in Base. - The 'compare and swap' operations should enforce memory ordering even when the exchange does not occur. - The exclusive monitor does not need to be cleared by CLREX if a LDRX was not followed by a matching STREX. - Use LDAR and STLR where possible. - Use the 'I' and 'J' constraints to hint for constants valid for immediate values Based on V8 changes at https://codereview.chromium.org/220793002 BUG=354405
