  XBZRLE: Fix qemu crash when resize the xbzrle cache

Resizing the xbzrle cache during migration causes qemu-crash,
because the main-thread and migration-thread modify the xbzrle
cache size concurrently without lock-protection.

  tcg-aarch64: Simplify tcg_out_ldst_9 encoding

At first glance the code appears to be using 1's compliment encoding,
a-la AArch32.  Except that the constant is "off", creating a complicated
split field 2's compliment encoding.

Much clearer to just use a normal mask and shift.
