[PATCH]Microblaze: Modified trap instruction

[Nagaraju Mekala]

Hello All,

    There is a bug in trap instruction generation.
    Instead of "bri 0" instruction "brki r0, -1" was used, corrected it now.
    
    ChangeLog:

        (trap): update in the pattern
        * gcc/testsuite/gcc.target/microblaze/others/builtin-trap.c
        (dg-final): update in the scan-assembler instruction
