This patch set fixes multiple instructions for PPC targets that were
producing incorrect results, or setting the wrong bits in FPSCR.
Patch 1 is just a style fix, trivial.
Patch 8 adds 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.
v1->v2:
- Squash patches 8 through 19 and write a better commit message to it.
- Dropped Daniel's R-b in the squashed patches, as the squash merged
both reviewed and non-reviewed patches. Now require a new, single
R-b.
