  [RISCV] Explicitly check for supported opcodes in optimizeCondBranch. NFC (#145622)

We don't support any of the immediate branches in this function yet so
explicitly exclude them rather than relying on isReg to return false.

Remove use of AnalyzeBranch. It doesn't help us much. Part of the code
was already getting the operands directly and it just complicated
creating a new branch.

I also inlined the modifyBranch function so we could use addReg on
BuildMI.
