Patch 1 is just a style fix, trivial. Patches 8 through 19 add helper_reset_fpstatus() calls to instructions that have an issue where the exception flags are being kept from the previous instruction, causing incorrect bits to be set, specially the non-sticky FI bit. Other patches fixes other specific situations.
