PowerPC floating point little-endian [2 of 15]

[Alan Modra <amodra at gmail dot com>]

This patch replaces occurrences of GET_LDOUBLE_* and SET_LDOUBLE_*
macros, and union ieee854_long_double_shape_type in ldbl-128ibm/,
and a stray one in the 32-bit fpu support.  These files have no
significant changes apart from rewriting the long double bit access.

In the following I make use of the fact that casting a long double to
double retrieves the high double, rather than calling ldbl_unpack
everywhere.

I generally resisted the urge to make formatting fixes in this series
of patches, thinking that would be better as a separate patch.
