Bcc (Branch Relative if Condition Satisfied)

This branching instruction has no delay slot.
If the conditions established for each particular instruction are satisfied, branch to the
address indicated by "label9" relative to the value of the program counter (PC). When
calculating the address, double the value of "rel8" as a signed extension.
If conditions are not satisfied, no branching can occur.
Conditions for each instruction are listed in Table 7.94-1.
