Paolo Bonzini 63fd8ef080 target/i386: implement SYSCALL/SYSRET in 32-bit emulators
AMD supports both 32-bit and 64-bit SYSCALL/SYSRET, but the TCG only
exposes it for 64-bit targets.  For system emulation just reuse the
helper; for user-mode emulation the ABI is the same as "int $80".

The BSDs does not support any fast system call mechanism in 32-bit
mode so add to bsd-user the same stub that FreeBSD has for 64-bit
compatibility mode.
