Changes since v3:
Rebased on master, and combined the JSConv and FHM patch sets.
There were a number of patch conflicts which needed fixing up.
Changes since v2:
Patch 2 splits out vfp_helper.c, which I wrote for something else.
But while rebasing it occured to me that helper_vjcvt is better placed
in vfp_helper.c than op_helper.c, so why not include it here and now.
Patch 3 corresponds to the v2 patch 1, but totally rewritten. What
I missed the first time around is that register Sn is encoded differenly
than Dn, so merely setting dp = 0 doesn't help because we've already
decoded the register number incorrectly. Therefore, replace some really
ugly if conditions and set some variables as appropriate.
Patch 4 is adjusted to match the change in decode from patch 2, and
putting the aa32 flags in the right place.
