deal with 64 bit registers.
* gcc/config/s390/s390.h: Define __zarch__ predefined macro.
Replace UNITS_PER_WORD with UNITS_PER_LONG where it is ABI relevant.
(UNITS_PER_LONG): New macro.
* libjava/include/s390-signal.h: Define extended ucontext
structure containing the upper halfs of the 64 bit registers.
