Use IR node's BranchNode field for IF/ELSE/ENDIF instructions.
This allows us to back-patch the IF/ELSE instruction's BranchTarget field
to point to the location of the ELSE/ENDIF instructions. No longer have to
search for ELSE/ENDIF in the interpreter. Also makes it trivial to translate
IF/ELSE instructions into conditional/unconditional BRA instructions.
