Make use of the new bit operation instructions when generating code
for the arch13 level.

gcc/ChangeLog:

2019-04-02  Andreas Krebbel  <krebbel@linux.ibm.com>

	* config/s390/s390.c (s390_canonicalize_comparison): Convert
	certain compares for arch13 in order to make use of the condition
	code result produced by the new instructions.
	(s390_rtx_costs): Adjust the costs for nnrk, nngrk, nork, nogrk,
	nxrk, and nxgrk instruction patterns.
	* config/s390/s390.md (ANDOR, bitops_name, inv_bitops_name)
	(inv_no): Add new code iterator together with some attributes.
	("*andc_split_<mode>"): Disable splitter for arch13.
	("*<ANDOR:bitops_name>c<GPR:mode>_cc")
	("*<ANDOR:bitops_name>c<GPR:mode>_cconly")
	("*<ANDOR:bitops_name>c<GPR:mode>")
	("*n<ANDOR:inv_bitops_name><GPR:mode>_cc")
	("*n<ANDOR:inv_bitops_name><mode>_cconly")
	("*n<ANDOR:inv_bitops_name><mode>", "*nxor<GPR:mode>_cc")
	("*nxor<mode>_cconly", "*nxor<mode>"): New insn definitions.
