Report captured variables in input dumps and traces.  For example:

  $ cat check
  CHECK: hello [[WHAT:[a-z]+]]
  CHECK: goodbye [[WHAT]]
  
  $ FileCheck -dump-input=always -vv check < input |& tail -8
  <<<<<<
             1: hello world
  check:1'0     ^~~~~~~~~~~
  check:1'1           ^~~~~ captured var "WHAT"
             2: goodbye world
  check:2'0     ^~~~~~~~~~~~~
  check:2'1                   with "WHAT" equal to "world"
  >>>>>>
  
  $ FileCheck -dump-input=never -vv check < input
  check2:1:8: remark: CHECK: expected string found in input
  CHECK: hello [[WHAT:[a-z]+]]
         ^
  <stdin>:1:1: note: found here
  hello world
  ^~~~~~~~~~~
  <stdin>:1:7: note: captured var "WHAT"
  hello world
        ^~~~~
  check2:2:8: remark: CHECK: expected string found in input
  CHECK: goodbye [[WHAT]]
         ^
  <stdin>:2:1: note: found here
