PowerPC floating point little-endian [2 of 15]

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.
