Mov "compress changes" functions in V8_COMPRESS_POINTERS

This fix build error(mksnapshot) on mips64el after
https://crrev.com/c/1526009. We should implements
"compress changes" functions on mips64, but now mips64 build
failed while enable pointer compression, we need port some
more pacth to mips64, for example: https://crrev.com/c/1477215
