The branch-relative-on-condition (BRC) instruction allows us to use an immediate to specify under what conditions the branch is taken. For example, `BRC $7, L1` is equivalent to `BNE L1`. It is sometimes useful to specify branches in this way when either we don't have an extended mnemonic for a particular mask value or we want to generate the condition code mask programmatically. The new load-on-condition (LOCR and LOCGR) and compare-and-branch (CRJ, CGRJ, CLRJ, CLGRJ, CIJ, CGIJ, CLIJ and CLGIJ) instructions provide the same flexibility for conditional loads and combined compare and branch instructions.
