target/microblaze: Ensure imm constant is always available
Include the env->imm value in the TB values when IMM_FLAG is set.
This means that we can always reconstruct the complete 32-bit imm.
Discard env_imm when its contents can no longer be accessed.
Fix user-mode checks for BRK/BRKI, which depend on IMM.
