IBM zSystems: Fix TARGET_D_CPU_VERSIONS
In the context of D the interpretation of S390, S390X, and SystemZ is a
bit fuzzy. The wording S390X was wrongly deprecated in favour of
SystemZ by commit
https://github.com/dlang/dlang.org/commit/3b50a4c3faf01c32234d0ef8be5f82915a61c23f
Thus, SystemZ is used for 64-bit targets, now, and S390 for 31-bit
targets. However, in TARGET_D_CPU_VERSIONS depending on TARGET_ZARCH we
set the CPU version to SystemZ. This is also the case if compiled for
31-bit targets leading to the following error:
libphobos/libdruntime/core/sys/posix/sys/stat.d:967:13: error: static assert: '96u == 144u' is false
967 | static assert(stat_t.sizeof == 144);
| ^
Thus in order to keep this patch simple I went for keeping SystemZ for
64-bit targets and S390, as usual, for 31-bit targets and dropped the
distinction between ESA and z/Architecture.
gcc/ChangeLog:
* config/s390/s390-d.cc (s390_d_target_versions): Fix detection
of CPU version.
