target/i386: Raise #GP on unaligned m128 accesses when required.

Many instructions which load/store 128-bit values are supposed to

target/i386: Raise #GP on unaligned m128 accesses when required.

Many instructions which load/store 128-bit values are supposed to
raise #GP when the memory operand isn't 16-byte aligned. This includes:
- Instructions explicitly requiring memory alignment (Exceptions Type 1
in the "AVX and SSE Instruction Exception Specification" section of
the SDM)
- Legacy SSE instructions that load/store 128-bit values (Exceptions
Types 2 and 4).

This change sets MO_ALIGN_16 on 128-bit memory accesses that require
16-byte alignment. It adds cpu_record_sigbus and cpu_do_unaligned_access
hooks that simulate a #GP exception in qemu-user and qemu-system,
respectively.

Merge remote-tracking branch 'remotes/rth/tags/pull-tcg-20211102' into staging

- Split out host signal handing from accel/tcg/user-exec.c
to linux-user/host/arch/host-signal.h
- Replace TCGCPUOps.tlb_fill with TCGCPUOps.record_sigsegv for user-only
- Add TCGCPUOps.record_sigbus for user-only
- Remove a lot of target-specific cpu_loop handling for signals,
now accomplished with generic code.

Use the maperr parameter to properly set PG_ERROR_P_MASK.
