the mapping for <name>l to <name>f128 when the long double default
is IEEE 128-bit.

We use the TARGET_MANGLE_DECL_ASSEMBLER_NAME hook to change this name. We
only do this if the default is that long double is IBM extended double, and
the user asked for IEEE 128-bit. */
only do this transformation if the __float128 type is enabled. This
prevents us from doing the transformation on older 32-bit parts that might
have enabled using IEEE 128-bit floating point as the default long double
type. */
