-----------
[JSC] DataViewSet should initialize tempFPR when the data byte size is less
than 8
https://bugs.webkit.org/show_bug.cgi?id=285363
rdar://142330774
Reviewed by Yusuke Suzuki and Keith Miller.
DataViewSet handles only three cases for floating-point data (data byte
sizes of 2, 4, or 8) in the DFG JIT compilation. The tempFPR is used
when the data byte size is less than 8. Therefore, we should define
tempFPR for a byte size of 2.
