PR 69400: Invalid 128-bit modulus result

As described in the PR, wi::divmod_internal was sign- rather than
zero-extending a modulus result in cases where the result has fewer
HWIs than the precision and the upper bit of the upper HWI was set.

This patch tries to make things more robust by getting wi_pack
to handle the canonicalisation step itself.

Tested on x86_64-linux-gnu.  I added tests to the wide-int
plugin since that seemed more direct.

S/390: Fix missing .size directives.

It seems at some point the .size hook was hijacked to emit some
machine-specific directives, and the actual .size directive was
forgotten.  This caused problems for split-stack support, since
linker couldn't scan the function body for non-split-stack calls.

* config/s390/s390.c (s390_asm_declare_function_size): Add code
to actually emit the .size directive.

S/390: Use proper read-only data section for literals.

Previously, .rodata was hardcoded.  For C++ vague linkage functions,
this resulted in needlessly duplicated literals.  With the new split
stack support, this resulted in link errors, due to .rodata containing
relocations to the discarded text sections.
