For example, in a test file, the following directives define a
`%{check}` substitution with two formal parameters and then use it
with varying actual arguments:

  // DEFINE: %{check}( CFLAGS %, FC_PREFIX %) =                   \
  // DEFINE:   %clang_cc1 %{CFLAGS} -emit-llvm -o - %s |          \
  // DEFINE:              FileCheck -check-prefix=%{FC_PREFIX} %s
  
  // RUN: %{check}( -foo %, FOO %)
  // RUN: %{check}( -bar %, BAR %)
