* config/xtensa/lib2funcs.S (__xtensa_libgcc_window_spill,

the register windows.

* real.h: Define REAL_VALUE_TYPE_SIZE as 96 or 160, as
appropriate. Document need for extended precision even when
MAX_LONG_DOUBLE_TYPE_SIZE is smaller. Define REAL_WIDTH here,
based on REAL_VALUE_TYPE_SIZE. Use REAL_WIDTH to size
REAL_VALUE_TYPE. Define CONST_DOUBLE_FORMAT here. Use #error
instead of relying on later syntax error when REAL_WIDTH > 5.
* real.c: Define NE based only on whether or not we have a
full 128-bit extended type (not INTEL_EXTENDED_IEEE_FORMAT).
Require sizeof(REAL_VALUE_TYPE) == 2*NE. Unconditionally
define GET_REAL and PUT_REAL as simple memcpy operations; no
need to byteswap or round.
Use #error instead of #ifdef-ing out the entire file, for
prompt error detection.
* rtl.c, gengenrtl.c: No need to calculate CONST_DOUBLE_FORMAT here.

set in c). This folds the zero/sign extension into the bit-wise and
operation.
