Tony Wasserka 51d355da30 Arm64: Fix bitmask used to match load/store instructions ...

When multiple threads simultaneously SIGBUS on the same address, one of them
will perform the backpatching while the other will detect the backpatched
instruction sequence and hence report the SIGBUS as "handled".

This typo broke the instruction detection logic: The second thread would
assume the source of the SIGBUS was unrelated to TSO emulation and hence
report the signal as unhandled (generally triggering program abortion).

In practice, this problem did not manifest as FEX does not currently share
CodeBuffers between threads.
