target-i386: fix set of registers zeroed on reset
BND0-3, BNDCFGU, BNDCFGS, BNDSTATUS were not zeroed on reset, but they
should be (Intel Instruction Set Extensions Programming Reference
319433-015, pages 9-4 and 9-6). Same for YMM.
XCR0 should be reset to 1.
TSC and TSC_RESET were zeroed already by the memset, remove the explicit
assignments.
