* Add riscv for capstone5 in the meson
* Report capstone version in the asm plugins
* Many changes in the ppc analysis, seems like it's improved, (emulation quality and xrefs)
* Update all tests and report issues in capstone4 to upstream
* Fix-x86-16 test marked as broken as it needs better fix
Detailed description
I've confirmed #16433 (comment) (including the nasm rax -> eax bug) and thus this pr
makes the x86_64 assembler use the MOV B8+ encoding (MOV r64, imm64) when the immediate
is between 0x80000000 and 0xffffffff for both:
Consistency with GNU assembler. It actually does seem to be the expected encoding.
This does mean that mov eax, 0xffffffff and mov rax, 0xffffffff will have very different semantics.
