Some instructions are passed to the assembler to be
transformed to the final instruction variant. An
example would be dsrll which is transformed into
dsll32 if the shift value is greater than 32.

For direct object output we need to do this transformation
in the codegen. If the instruction was inside branch
delay slot, it was being missed. This patch corrects this
oversight.
