("linux-user: Clean up siginfo_t handling")
Changes for v3:
* Rebase on siginfo_t patch set -- while probably only
force_sig_fault is required, I suspect minor conflicts
with the other cleanups.
* Typo fix.
Changes for v2:
* Handle the exceptions in cpu_loop.
* Fix how the instruction is raised for aa32 el1.
* Add pc alignment test cases.
