Based-on: 20210918184527.408540-1-richard.henderson@linaro.org
("linux-user: Streamline handling of SIGSEGV")

which is in turn based on at least 3 other patch sets, so:

  https://gitlab.com/rth7680/qemu/-/commits/tcg-siginfo

Changes since v2:
  * Rebase on top of sigsegv cleanup, which eliminates about
    half of the places that needed updating to force_sig_fault.
  * target/mips cleanups+fixes for EXCP_BREAK and EXCP_TRAP.

Apologies to Phil and Peter, who gave me r-b on v2, which I failed to pick into this patch 
set.  I'll remedy that for v4.
