Raise pc alignment faults.
Fix single-step and pc-align priority over breakpoints.
Not yet fixing insn abort priority over breakpoints.

Based-on: 20210813131809.28655-1-peter.maydell@linaro.org
("linux-user: Clean up siginfo_t handling for arm, aarch64")

Changes for v2:
  * Handle the exceptions in cpu_loop.
  * Fix how the instruction is raised for aa32 el1.
  * Add pc alignment test cases.
