[JSC] Use allocated scratch FPR for ARM64 countPopulation
https://bugs.webkit.org/show_bug.cgi?id=257753
rdar://110327985
Reviewed by Justin Michaud.
fpTempRegister is not available in Air, so we should not use it in ARM64
countPopulation implementation.
This patch explicitly allocates FPR scratch register to use it in ARM64
countPopulation.
