[JSC] Use ZeroReg for store8 / store16 in ARM64 B3/Air
https://bugs.webkit.org/show_bug.cgi?id=257070
rdar://109591267
Reviewed by Justin Michaud.
This patch extends B3/Air to use ZeroReg for store8 / store16 in ARM64.
This allows us to remove zero-stored register usage further, which can reduce
register pressure.
