* 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.

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.
