Martyn Capewell 0d5b0d7365 [arm64] Enforce restriction on stlxr instructions 
The stlxr (store-release exclusive register) instructions in Arm64 have similar
restrictions to Arm's strex instructions - the status register must not alias
the source or address registers.

Enforce this in the assembler and simulator, and modify Turbofan and cctest to
conform to this. Also, make a small improvement to the code generated for
compare and exchange.

This is a port of 44c52f7bb5.
