  -----------
  [FileCheck] Fix parsing empty global and pseudo variable names (#82595)

In `Pattern::parseVariable`, for global variables (those starting with
'$') and for pseudo variables (those starting with '@') the first
character is consumed before actual variable name parsing. If the name
is empty, it leads to out-of-bound access to the corresponding
`StringRef`.

This patch adds an if statement against the case described.
