PR rtl-opt/13987
* config.host (use_long_long_for_widest_fast_int): New, default is
off.
(ia64-*-hpux*): Enable use_long_long_for_widest_fast_int.
* configure.ac: If use_long_long_for_widest_fast_int, then
define USE_LONG_LONG_FOR_WIDEST_FAST_INT.
* configure: Regenerate.
* config.in: Regenerate.
* hwint.h (HOST_WIDEST_FAST_INT, HOST_BITS_PER_WIDEST_FAST_INT):
New: widest integer type supported efficiently in hardware for the
host.
* sbitmap.h (SBITMAP_ELT_BITS): Define based on
HOST_BITS_PER_WIDEST_FAST_INT.
(SBITMAP_ELT_TYPE): Define based on HOST_WIDEST_FAST_INT.
* hard-reg-set.h (HARD_REG_ELT_TYPE): Define based on
HOST_WIDEST_FAST_INT
instead of HOST_WIDE_INT.
(HARD_REG_SET_LONGS): Likewise.
(UHOST_BITS_PER_WIDE_INT): Likewise.
Change the checks for the fast cases to be based on
HOST_BITS_PER_WIDES_FAST_INT instead of HOST_BITS_PER_WIDE_INT.
