[ARMv7] Avoid unaligned strd
https://bugs.webkit.org/show_bug.cgi?id=293694
Reviewed by Yusuke Suzuki and Sosuke Suzuki.
Not all armv7 chips are required to suport unaligned strd instructions.
For example, my Neoverse N1 does not support it.
This is documented at
https://developer.arm.com/documentation/100748/0624/Alignment-support-in-Arm-Compiler-for-Embedded-6/Aligned-and-unaligned-accesses.
We should remove these lowerings to support all armv7 processors.
In the future, we may want to add them back when we can handle
the alignment check separately.
