target-mips: Use local float status pointer across MSA macros
Reduce line wrapping throughout MSA helper macros by using a local float status pointer rather than referring to the float status through the environment each time. No functional change. Backports commit 1a4d570017bf35d99340781ecb59dd3772464031 from qemu
