* config/sparc/sparc.md (movsf_const_intreg): Add constraints for
regclass' sake.
(movdf_const_intreg_sp32): Likewise. Prefer the memory load
alternative because setting up 64bit constant is usually costly,
especially when reload is in progress or completed.
(movdf_const_intreg_sp64): Likewise.
(movdf_const_intreg split): Fix building up constants when
HOST_BITS_PER_WIDE_INT is 64 yet long is 32bit.
