  BBQJIT: work around invalid instruction selection on ARMv7
https://bugs.webkit.org/show_bug.cgi?id=280891

Reviewed by Justin Michaud.

For encoding reasons, not all register arguments to sub are compatible
with a destination of sp on ARMv7. Work around this by using a scratch
register as the destination (on ARMv7 only).
