Consider a NOCE conversion as profitable if there is at least one
conditional move.
gcc/ChangeLog:
* config/s390/s390.cc (TARGET_NOCE_CONVERSION_PROFITABLE_P):
Define.
(s390_noce_conversion_profitable_p): Implement.
gcc/testsuite/ChangeLog:
* gcc.target/s390/ccor.c: Order of loads are reversed, now, as a
consequence the condition has to be reversed.
---
Bootstrapped and regtested on s390. Ok for mainline?

I guess GET_MODE_SIZE(Pmode) should be UNITS_PER_WORD here to enable the conversion also for 64 bit
modes with -m31 -mzarch.
Ok with these changes. Thanks!

Since the patch works fine so far for mainline, ok to backport to GCC 14?
