2015-07-15target-mips: fix to clear MSACSR.CauseYongbok Kim
MSACSR.Cause bits are needed to be cleared before a vector floating-point instructions. FEXDO.df, FEXUPL.df and FEXUPR.df were missed out.

2015-03-11target-mips: add missing MSACSR and restore fp_status and hflagsLeon Alrae
Save MSACSR state. Also remove fp_status, msa_fp_status, hflags and restore them in post_load() from the architectural registers. Float exception flags are not present in vmstate. Information they carry is used only by softfloat caller who translates them into MIPS FCSR.Cause, FCSR.Flags and then they are cleared. Therefore there is no need for saving them in vmstate.

2014-12-16target-mips: Use local float status pointer across MSA macrosMaciej W. Rozycki
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.
