d356312fdc target-arm: Clean up handling of AArch64 PSTATE
The env->pstate field is a little odd since it doesn't strictly
speaking represent an architectural register. However it's convenient
for QEMU to use it to hold the various PSTATE architectural bits
in the same format the architecture specifies for SPSR registers
(since this is the same format the kernel uses for signal handlers
and the KVM register). Add some structure to how we deal with it:
 * document what env->pstate is
 * add some #defines for various bits in it
 * add helpers for reading/writing it taking account of caching
   of NZCV, and use them where appropriate
 * reset it on startup

978fae9f1a linux-user/signal.c: Avoid using uninitialized data in ARM sigreturn
Rephrase code used in ARM sigreturn functions to avoid using
uninitialized variables. This fixes one genuine problem ('frame'
would not be initialized if we took the error-exit path because
our stackpointer was misaligned) and one which is clang being
alarmist (frame_addr wouldn't be initialized, though this is
harmless since unlock_user_struct ignores its second argument
in these cases; however since we don't generally make use of
this not-really-documented effect it's better avoided).

b04636f866 linux-user/signal.c: PPC: Silence clang uninitialized-use warning
Silence a clang warning in a PPC signal return function:

/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/signal.c:4611:9: error: variable 'sr_addr' is used
      uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
    if (!lock_user_struct(VERIFY_READ, sc, sc_addr, 1))
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/signal.c:4636:28: note: uninitialized use occurs here
    unlock_user_struct(sr, sr_addr, 1);
                           ^~~~~~~
/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/qemu.h:442:27: note: expanded from macro 'unlock_user_struct'
    unlock_user(host_ptr, guest_addr, (copy) ? sizeof(*host_ptr) : 0)
                          ^

This happens when we unlock a user struct which we never
attempted to lock. Strictly, clang is actually wrong here -- it
hasn't been able to spot that unlock_user_struct() doesn't use
its second argument if the first is NULL. However it doesn't
seem too unreasonable to demand that we pass in initialized
values to it.

1239b472bb linux-user: Save the correct resume address for MIPS signal handling
The current ISA mode needs to be saved in bit 0 of the resume address.
If the current instruction happens to be in a branch delay slot, then
the address of the preceding jump instruction should be stored instead.
exception_resume_pc already does both of these tasks, so it is
made available and reused.

MIPS_HFLAG_BMASK in hflags is cleared, otherwise QEMU may treat the
first instruction of the signal handler as a delay slot instruction.

ea3164aafc linux-user: Fix MIPS ISA transitions during signal handling
Processors supporting the MIPS16 or microMIPS ISAs set bit 0 in target
addresses to indicate that the target is written using a compressed ISA.

During signal handling, when jumping to or returning from a signal
handler, bit 0 of the destination PC is inspected and MIPS_HFLAG_M16 in
hflags cleared or set accordingly.  Bit 0 of the PC is then cleared.

This change is already present in glibc 2.15.90, so qemu compilation

(it's a qemu internal check, which is done wrong only for this
architecture, it's more a typo than a bug). It's NOT ppc specific,
it's POSIX standard (sigaltstack) and qemu internal.

Suppress a gcc array bounds overrun warning when filling in the SPARC
signal frame by adjusting our definition of the structure so that the

964413d9d9 linux-user: ARM: clear the IT bits when invoking a signal handler
When invoking a signal handler for an ARM target, make sure the IT
bits in the CPSR are cleared. (This would otherwise cause incorrect
execution if the IT state was non-zero when an exception occured.
This bug has been masked previously because we weren't getting the
IT state bits at exception entry right anyway.)

Also use the proper cpsr_read()/cpsr_write() interface to update
the CPSR rather than manipulating CPUState fields directly.

- ucontext.uc_sigmask is declared with type long int, while it is

0b1bcb00fb MIPS signal handling fixes.
Also fixes a register corruption bug in do_sigreturn. When "returning"
from sigreturn we are actually restoring the virtual cpu state from the
signal frame.  This is actually surprisingly hard to observe in practice.

Typically an thread be blocked in a FUTEX_WAIT call when the signal arrives,
so the effect is a spurious syscall success and the introduction of a
subtle race condition.

On x86/arm a syscall modifies a single word sized register, so
do_sigreturn can just return that value.  On MIPS a syscall clobbers
multiple registers, so we need additional smarts.  My solution is to
invent a magic errno value that means "don't touch CPU state".

The proper exit code for dieing from an uncaught signal is -<signal>.
The kernel doesn't allow exit() or _exit() to pass a negative value.
To get the proper exit code we need to actually die from an uncaught signal.

A default signal handler is installed, we send ourself a signal
and we wait for it to arrive.
