[PULL 22/28] linux-user/sparc: Handle priviledged opcode trap

[Laurent Vivier]

From: Richard Henderson <richard.henderson@linaro.org>

For the most part priviledged opcodes are ifdefed out of the
user-only sparc translator, which will then incorrectly produce
illegal opcode traps.  But there are some code paths that
properly raise TT_PRIV_INSN, so we must handle it.
