1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.

are useful for dataflow analysis: CFGStmtVisitor and DataflowStmtVisitor.

CFGStmtVisitor is the same as StmtVisitor is that it has separate visitors
for "root" statements in a CFGBlock (statements that have a designated
slot int the list of statements in a CFGBlock).  It also recognizes statements
that have implicit control-flow, and calls special visitor methods for those.

DataflowStmtVisitor extends CFGStmtVisitor to serve as a template for
implementing transfer functions.  It does a pre-/post-order traversal of
substatements depending on whether we are doing a forward/backward analysis.
It also has special handling for implicit-control-flow statements so that
they are visited only once.
