This patch adds a file for all the FPU related helpers with all the includes,
useful defines, and a function to update the status bits. Additionally it adds
a mask for the rounding mode bits of PSW as well as all the opcodes for the
FPU instructions.

psw_read() ought to sync the PSW value with the
cached status bits (C,V,SV,AV,SAV). For this the bits
are cleared in the PSW before they are written from the
cached bits. The clear mask is too big and clears two
additional bits.

Wrong braces on the restore of the cached TCGv SV and V bit could lead to
a wrong PSW. While at this it removes unnecessary braces for the restore
of the cached TCGv AV and SAV bits.
