[PATCH v1 0/8] small refactorings before posting PAuth_LR patch series

[Matthieu Longo]

This patch series contains some refactorings / minor improvements required for a future PAuth_LR patch series.
Not much to say about commits 1 to 6, they are self-explanatory.
Commit 7 introduces a new operand flag for unsigned immediate value. This is a new use case introduced for auti<k>sppc (a PAuth_LR instruction) that takes, as its first operand, an unsigned PC relative offset.
Commit 8 refactors the binary approach for the RA signing method which was not extendable. PAuth_LR will add a 3rd value for the RA state.

Regression tested on aarch64-unknown-linux-gnu, and no regression found.

Ok for binutils-master?

Regards,
Matthieu.
