to be returned incorrectly.

Handle failure of get_user accessing the semihosting

  Log Message:
  -----------
  target-m68k/m68k-semi.c: Log when put_user for returning values fails

Abstract out the use of put_user for returning semihosting call results,
so that we can log when a guest erroneously attempts a semihosting call
with an unwritable argument block.

  tcg: Add extended GETPC mechanism for MMU helpers with ldst optimization

Add GETPC_EXT which is used by MMU helpers to selectively calculate the code
address of accessing guest memory when called from a qemu_ld/st optimized code
or a C function. Currently, it supports only i386 and x86-64 hosts.

  tcg: Optimize qemu_ld/st by generating slow paths at the end of a block

Add optimized TCG qemu_ld/st generation which locates the code of TLB miss
cases at the end of a block after generating the other IRs.
Currently, this optimization supports only i386 and x86_64 hosts.
