EXCEPTION_PROLOG_0 and EXCEPTION_EPILOG_0 were added some time ago in order to regroup the two mtspr/mfspr to SCRATCH0 and SCRATCH1 and the mfcr/mtcr in order to ease entry and exit of function not using the full EXCEPTION_PROLOG. Since then, the mfcr/mtcr has been taken out, hence just leaving the two mtspr/mfspr in the macro. In order to improve readability of the exception functions, we remove those two macros and copy back the two mtspr/mfspr instead. As r10 and r11 are used for SCRATCH0 and SCRATCH1, lets also use r12 for SCRATCH2. It will also improve the readability/maintenance.
