<p>The first check line matches a regex (%[a-z]+) and captures it into the
variables "REG". The second line verifies that whatever is in REG occurs later
in the file after an "andw". FileCheck variable references are always contained
in [[ ]] pairs, are named, and their names can be formed with the regex
"[a-zA-Z][a-zA-Z0-9]*". If a colon follows the name, then it is a definition of
the variable, if not, it is a use.</p>

<p>FileCheck variables can be defined multiple times, and uses always get the
latest value. Note that variables are all read at the start of a "CHECK" line
