Raise pc alignment faults.
Fix single-step and pc-align priority over breakpoints.
Not yet fixing insn abort priority over breakpoints.
r~
Changes for v4:
* Rebase on master.
* Split some cleanups into new patches.
* No special cases in helper_exception_pc_alignment.
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.
